MacBook Pro 16' 2019 constant crashes

Two months ago my MBP started to crash, mostly during hibernation, but not only.

I've run default system diagnostics (no errors found, no issues with the disk) + reinstalled the system + run all the updates multiple times.

Additionally, I've run MemTest86. Reports below.

System info:

-2,4 GHz 8-Core Intel Core i9

-Intel UHD Graphics 630 1536 MB

-64 GB 2667 MHz DDR4

-Macintosh HD

-C02C94DGMD6

-OS: 14.2.1 (23C71)

No custom parts in this one. Only opened it once by some service few months ago to clean it inside. There was an issue with charging after that but quickly it got fixed by the same service by plugging everything it once again.

Crash report message examples:

Kernel trap at 0xffffff800d8617a5, type 14=page fault
Possible memory corruption: pmap_pv_remove

The crashes are inconsistent, i.e. different messages and processes crashes are displayed in the crash reports.

Unfortunately it seems that my system doesn't store all the reports (checked in /Library/Logs/*).

I will provide more data as soon as one occurs.

Below is the MemTest86 report:

From what I've read, this particular test(Test 13 Hammer Test) may not conclude that the memory is broken.

What other options do I have to find the issue with my laptop?

I can offer the following observations after looking at your Etrecheck report:

Open VPN: Is this needed to connect to a corporate server? If not, many VPN apps don't play well with Macs (and, honestly, probably aren't even needed)
Karabiner: Again, is this an app you truly need?
Bitwarden: This password manager seems a bit sketchy to me. I've always used 1Password, and feel it's the best solution out there.
No Time Machine backup configured. (Kinda like walking a tightrope with no safety net, IMHO).

All the above being said, Kernel panics are often caused by hardware issues. My recommendation would be to bring your Mac in to the Apple Store and have their tech run diagnostics (which are more thorough than the Apple "consumer" diagnostics us mere mortals are allowed to use).

hey guys, i’m desperate to figure out what is the issue here. I created a separate profile on the MB and it crashes there as well. The safe boot works fine, although very slow (which is expected) and has not crashed so far. I would really appreciate any help in terms of figuring out what piece of software / hardware is bad here.

please help 🙏🏻
