After I I've updated to the latest release of macOS, I've experienced a weird bug every time I leave my laptop closed (still on) for more than a couple hours and plugged in.
It reboots and states the message/log below.
Not sure what they changed but this did NOT happen before the update.
Things I've tried:
I still experience this issue everyday.
I have the same model laptop and am experiencing the same issues as you've described ever since updating to 10.15.4.
I received a brand-new Macbook Pro 16, i9, Radeon Pro 5500M a week ago, created a new user connected to iCloud and moved some applications and data to the new device and upgraded to 10.15.4. After I saw the same problems described above I tested the following, partly with the help of apple support (2 calls made), partly on my own:
Reformatted the disk and reinstalled 10.15.4 from scratch, created a new user and configured it with my iCloud during initial user setup. No data or settings transferred from my old machine.
SMC Reset
PRAM/NVRAM Reset
No other applications or device drivers (kernel extensions) installed
No other peripherals connected, no monitor connected, only the power supply via USB-C
created a test user, without configuring iCloud during setup.
Observations:
1) With my own user, putting the macbook to sleep (closing the lid), waking it up again (opening the lid) after 5 minutes: no problem, login via touch id possible.
2) With a test user, putting the macbook to sleep, waking it up again after 5 minutes: no problem, login via touch id possible.
3) With my own user, putting the macbook to sleep, waking it up again after more than 1 hour: laptop starts with white apple displaying and progress bar, thereafter touch id not possible, need to enter password, kernel panic report is shown after login. This behaviour is 100% reproducible, each time I leave the macbook in sleep mode for more than one hour.
4) With a test user, putting the macbook to sleep, waking it up again after more than 1 hour: no problem, login via touch id possible
5) With my own user, power nap disabled, waking it up again after 6-8 hours: no problem, login via touch id possible.
Conclusion: disabling power nap is a workaround for me. I haven't experienced the kernel panics in sleep mode thereafter.
I called apple support, told them I believe 10.15.4. has a bug with the new Macbook Pro 16, i9. Told them that it seems I am not the only person experiencing this problem, offering to give the this thread id, also mentioning a second thread.
apple support level 1 passed me on to level 2. Level 2 support told me he couldn't find in his support database anything regarding kernel panics after sleep with 10.15.4. He wasn't interested to be pointed to this thread and told me that to me it may look like a problem of general interest, but they receive so many reports, and my single call wouldn't be sufficient for him to escalate that further to engineering. He would need more proof to do that.
As the Macbook is brand-new, I expressed my concern that it might be a HW fault and that I would like to have the HW exchanged to exclude that it's a problem of my specific device. He said "he doesn't believe" that it's a HW problem.
He looked into his support instructions and asked me, if I had any third party kernel extensions, to which I told him (again) that it's pure 10.15.4., not even data copied from the old machine.
He looked into his support instructions and told me I could narrow down the problem, if I wanted to, by keeping power nap on, and disabling cloud services one by one, to see if it makes a differences. To which I answered that each test would take more than one hour and I would prefer that Apple engineering or quality assurance spends their time debugging. Rather than a customer who just spent a considerable amount of money for a brand new device.
So my confidence that Apple will take care of this problem soon is rather low. Apple support also told me he believed that if it's a general problem Apple engineering will become aware of it and fix it at some point in time, but he cannot tell me when.
That was long, but if you read until here thanks for letting me vent. :-)
I hope an Apple engineer sees this and fixes it in 10.15.5!
There’s more to the conversation
Read all repliesI have the same model laptop and am experiencing the same issues as you've described ever since updating to 10.15.4.

I've the same model and experiencing the same kernel panics while laptop is sleeping
Have you tried uninstalling VirtualBox?
There is an uninstaller on the installation dmg.
None of your Samples have anything useful in them. You cut off the useful bits.
@Barney-15E sorry ;)
Any of these may be the cause. Same advice as above.
com.adguard.nfext 27
com.paloaltonetworks.kext.pangpd 5.0.8f4
com.radiosilenceapp.nke.filter 2.2
I just experienced a different message on the reboot error reporting popup.
It looks like it's related to the recent Graphic driver changes in 10.15.4 when the computer goes to Sleep.
Same: MBP 16" 2019, 10.15.4, 2.4ghz 8-Core i9, 32GB DDR4, Intel UHD 630 1536 MB.
After leaving laptop for some time (mostly lid closed, but sometimes lid open asleep with and without external display), it has been rebooted and shows the kernel panic form to submit to Apple. Only happening after update to

And, you still have third-party kernel extensions loading.
The two primary causes of kernel panics are hardware faults and third-party kernel extensions. Removing the latter is the easiest to rule out.
If it still panics without any third-party kernel panics, then the high likelihood is some hardware fault.
However, Apple may have release bad GPU kernel extensions with this update, so that also could be a cause. That is almost unheard of, though.
I have exact same problem after u[date to 10.15.4 every time MBP 16 go to sleep I get Kernel Panic message (connected to external monitor and lid closed).
I have the exactly same issue.
Do you know any solution?.
Thanks.
I have the same model laptop and am experiencing the same issues as you've described ever since updating to 10.15.4.
My MBP is connected to multiple external monitors and lid is closed. When I use the MBP without the external monitors everything seems to be fine.
Before updating to 10.15.4 I never had any similair problems.
Same here. Brand new Macbook Pro 16'' (1 week old). After updating to Catalina 10.15.4 only when plugged in. Found another thread on the topic here https://forums.macrumors.com/threads/new-macbook-kernel-panics.2228308/. Still no solution, just a workaround (look at one of the last comments).
Let's wait for an update, hope that Apple Support knows about the issue.
I completely removed VirtualBox using the uninstaller script in the latest .dmg (from their website) and my system appears stable again.
