Crashing problem

its really annoyng them it crashes but i think is understandable

Check how many pages of addons you got 14 pages is reccomended, if you have more that might be the reasson but also you might have some corrupt addon files

Disable a few other addons to see if an unrelated addon is actually to blame. Then troubleshoot from there

reinstall your Addon or try to re-install your gmod...

Reinstall the game, update the computer driver, and check the integrity of the game cache, do not thank

Maybe you should buy a new pc u can get one from bestbuy, walmart or currys pc world obviously depending where you live
