After Effects / Windows 11 GPU freeze or hang with Nvidia 2080 Ti on alt tab - my fix

You have no idea how helpful was your solution...
T_T    Thank you so so much!!!!!

This fixed all my problems. Everything is lightning fast and the computer doesn't lock up doing nothing to 10-60 seconds at a time anymore. It wasn't just locking up AE, it was the whole PC. I have a GTX 3090.

Thanks for the solution. 

Every time I switched After Effect window to any other window in WIN11 I had a system crash, for the whole year this problem caused me irreparable mental trauma. And with only one f***g After Effect this problem. I've already invented a whole ritual to make sure I don't freeze up once again . WtF Adobe???

This didn't work for me unfortunately. 

So guess there is still no fix for this? Even after upgrading CPU and RAM this problem still accures. I have also seen people having this problem with all sort of different hardware types so this doesnt seem to be the problem here.

Big Thanks mate !!!. 
it really fix the problem.
idk why, but this hardware accel just crashing randomly.
it does feel a little bit faster in scrubbing my ae comp when its activated.
but the crash is really unbearable. 

Hope adobe fix this problem soon.

Didn't work in my case ;/. I hate that because I use AE linking on my daily basis, and sometimes I waste 1 hours on restarting PP and AE and my monitors. But what I have notice for ex. when I fnish single task in AE and move really quick to PP (so I alt+tab) its mostly likely the moment when PC freezes. But when I finish my job in AE then wait like 2 seconds before I alt+tab to PP it never crash, if so its so so rare almost never lets say. I'm not sure about other WinOS version but I never had to issues on Win10, currently I use Win11 with all possible updates. And as many I have done several installations of different GPU drivers and also did something in registry that might cause the problem, but it didn't help either. At some point I was thinking maybe its because of multi monitor setup. So I started to use only 1 for few hours, and same thing. Sometimes (which is even more strange) moving RAW files to PP when loading those files it crash especially when RAW files are like 300GB+, like what the hell... And I don't know but I feel like the issue in on Adobe side. And I always wonder what Am'I paying for if such issues is waste my time... Or maybe that problem is with hardware, my is 5800X, 3060 and 64GB RAM. Anyway I was hoping that this thread might be solution for me but unfortunatley wasn't ;/

Hi pacey-j!
I've just rolled back to windows 10 for a similiar issue.
After Effects (and sometimes Premiere too) were crashing and sometimes freezing all my system.
After several seconds and a black screen on both monitors the systems became responsive again, but I've always needed to restart afterfx or reboot the system to keep working.
I'm using MtMograph Motion too, but after a fresh windows 11 install, with no plugins, AfterFX was crashing again.
May I ask you, you're using an AMD Ryzen 3000 series?
I've got 2 identical system in studio, both experiencing the same issue. The only fix I found was rolling back to 10, sadly, cause I like those shiny rounded corners of 11 o((>ω< ))o
