MBP (15-inch, 2018) completely freezes, forced to restart with power button

[lorikku]

Lately my MBP has been having this weird issue where it just completely freezes, and there's nothing I can do with it anymore. The only thing that still works is my cursor, which I'm able to move everywhere, but that's it. No sound, no visual feedback, my desktop just completely freezes, forcing me to restart it by holding down the power button.

Occasionally, it has happened that my MBP just immediately crashes instead of freezing, which according to the crash report was caused by a kernel panic caused by the WindowServer being unresponsive.

So according to my current diagnostics, it seems that the WindowServer keeps getting unresponsive, which I think is the cause of the freezes as well... The freeze happens anywhere from 0 to 10 times a day, it's very random.
Crash report can be found here: https://pastebin.com/PfnWgAap

I don't know how to tackle the issue, or what to do to fix it. I don't know what causes the WindowServer to stop working either.

What I've tried so far:

• Upgraded to the latest MacOS version
• Done a thorough clean-up of my mac
• Reset the NVRAM/PRAM
• Reset the SMC
• Done a Disk Util first aid (no faults detected)
• Ran my MBP in diagnostic mode (no faults detected)

I hope someone can help me out here, as it's really annoying and I do need it to do my job properly. Thanks in advance!

Try going to Apple and see what they diagnose it with.

Decided to wipe my laptop completely and then re-install MacOS on it. This seems to have solved the problem, so I guess it was either some malware or just a faulty software issue. Thread resolved.

Wow, I wasn't going to suggest such a drastic measure, but ok. If it works fine, glad it did.

Will this cost me anything? I was able to contact an official Apple affiliate, which is also the place where I bought my MBP, and they said it'll cost me 50 bucks just for diagnostics.

I think I might still do this though, just wanna know if there is maybe a way to get around this without spending any money, as I'm not going to invest money into fixing it anyway, rather I'd buy a new laptop.

Looking at the last pastebin (https://pastebin.com/9miJ7480), it seemed that the issue was something else this time (namely the power management of the dGPU).

Knowing this I tried resetting the NVRAM (NOT SMC) as it seemed that an assignment of a value inside a RAM address basically failed. So far no crashes or freezes anymore. Will keep updating if anything happens, after which I will also try to reset the SMC.

The reason for this is so that I can kind of diagnose if the NVRAM reset fixes it (or not), after which I'll see if the SMC fixes it (or not).

So far, almost a week later, resetting the NVRAM seems to have solved the issue. Haven't had any crash at all, perfectly working laptop again

So, to conclude (maybe temporarily), to fix the issue to this thread:
1. Reset MBP (completely wipe the hard disk)
2. Reset NVRAM
