MBP 16" 2019 CRASHES WHILE SLEEPING

I have same issue since a couple of weeks, did all the resets recommended, not yet reinstall Catalina. Which apple supports requested. They said than I have to contact the display manufacturer :(

The PowerNap disabling did not help in my case.

Having the same issue since weeks - confronted with apple support recommending the usual things and finally to contact the display manufacturer. Ha, you need to search 10s in google to find that tons of users have the same problem and no OS reinstallation helps. Having tried all recommended septs - also disabling power nap does not help in my case.

I've had the same problem, MacBook Pro 16 crashes and reboots after being put to sleep. The problem did not repeat in Safe Mode nor when I disconnected all peripherals. I use an external display, 21" Cinema Display, and the MacBook Pro 16 sits under my desk when being used at home.

This problem persists when the MBP lid is closed. When I leave the MBP lid open, the problem goes away and the computer does not crash and reboot during sleep mode and acts completely normal with all peripherals attached. That is the solution that I found so that I can get back to work and all is well. ...with the lid open and the brightness turn down.

The cable coming from the 20" Cinema Display is fixed from the Display. I did try changing the USB-C to DVI adaptor to another one and yielded the same results. I agree to always check cables but in this case, all is well until the external monitor is attached and the MBP16 lid is closed. I don't know the absolute solution but this is what I've done to eliminate the sleep-crash-reboot routine.

I tried resetting the SMC. It seemed to work for a few hours and then went back to it's troubled state. I'm back to keeping the lid open as I'm using an external screen and all is well. Just a fix, not a solution

I tried resetting SMC according to Apple support after both updates. Same issue occurs. This time it actually rebooted again while I was using the computer( about 2-3 minutes in). I disabled power nap same problem. Going to call Apple back just to keep a log going. This will be the 4th call

I did the PRAM and SMC reset with no luck. I did the disk utility repair. I am not going to erase the hard drive and start over.

It does appear that it happens when connect to an external monitor. Obviously something changed with one of the last two updates. I did not have any issues until about 3 or 4 weeks ago and have not added any software.

Apple needs to send an update out to fix this.

Unfortunately, sometimes files get corrupted during updates. That may be what happened to myself and yourself. I know completely erasing a hard drive seems drastic, but if you have a good time machine back up, a few hours of copying data may get you back up and running in a fully functioning state. My 2017 MacBook Pro is running great again. Hope all works out! Hello

MBP 16 as well: 90% I'm connected to external monitor as well (BENQ PD2710QC, with single video/power TB3 cable).

And I cannot anymore put the Mac in standby... 'cos it panics.

That's a pain to remember to shutdown every night and starting up again in the morning. Other than having disabled the sleep during the day (consuming a lot more of electricity).

In previous Catalina, with my old 2018 15" I never had a problem.

I thought my crash was happening only when the computer was connected to my external display, but I have disproved that. It seems the crash happens when just the dongle is connected. The crash happened in safe mode. Today I reinstalled the OS and the crash happened yet again. So this is a big problem. I worry that I could see the same crash happen in a replacement. This is totally not cool.

I am in the same situation with my 16 inch MBP. I plug in to 34inch display via HDMI dongle and close lid with bluetooth apple keyboard/mouse and speaker. The shouldn't be an issue, but is, in that I have to reboot every time I walk away for more than <x time for computer to go to sleep> because it crashed -- life long Apple user and very disappointed.

My dear... I already got crazy in porting a couple of weeks ago my old MBP 15 2018 to 16 2019 with Time Machine (missed compatibility of Catalina with some external SSD controllers like JMS583 vA0 with unmanageable panics), and after several (6!) erases of the internal HD from recovery mode (redownloading the fresh OS from web), I was able - with an old SSD - to port the old Mac with Time Machine. Yet Time Machine does not 100% port all the system settings, so I spent another week in reconfiguring (or reinstalling) some apps and parameters. Consider my 512GB disk is always "full" of work apps (Adobe suite, Rhino, FCPX with tons of plugins, Xcode, several minor tools, Cura, Choregraphe for robotics, etc.) and I usually travel with a 2TB NVMe SDD connected and attached to the cover lid...

Nonetheless, even after this ton of reinstalls, the "fresh" system immediately did not work...

So I won't erase again everything, losing 1 week of my time on such an expensive machine: Apple MUST solve this issue...

I know! I've been waiting for a fix myself. I have talked to apple support on the phone, in store at Genius bar, no one can help. I don't want to erase my entire computer. XCODE is buggy enough to have to reinstall all the things it requires will eat up a day at least.

Apple, we need a fix ASAP!

Yes, my MBP 16 is still crashing, whatever solution I try.

And I will NOT erase everything another time (my MBP has 2 weeks of life)... too much work to do...

Apple has to solve the situation directly...

Brand new Mac Book 16 with the latest Catalina (MacOS X 10.15.5 (19F101)) is now crashing every single time it goes into sleep mode. The kernel panic seems to be in the same place every time. I hope there's a software update to fix this.
