Lua panic error garry's mod! pls help

Hello there this is the classic one. I upgraded to windows 10 today but i already had the problem on windows 8.1 so thats not the problem. I have tried to reinstall gmod about 20 times, i have deleted all addons and workshop files, i have done the vram thing with -heapsize. With the heapsize thing i can now join servers but after a few minutes i crash. I hef good pc and have never had any problems with this before.

Can you post your computer specs?

Intel Core i7-4790K
HyperX Savage DDR3 2400MHz 16GB
MSI GeForce GTX 980 4GB

Are you still subscribed to the addons? There is the possibility that they have redownloaded.
If you’re running quite a few adodns it could be that a problematic one is causing the error.

yeah i have unsubscribed and deleted.
