Game keeps crashing but all other similar posts are not quite the same problem

i am playing Gmod TTT usually and every now and then, mostly when i die, my game freezes, loops a bit of sound then crashes. is there any help for my game? or is it permanently buggered?

Verify game integrity on Steam by right clicking “Garry’s Mod” clicking Local Files and then clicking

After doing that is there anything else that i got to do? or does that fix it?
it said two files failed… i am not really sure of what i need to do.

-EDIT.
I tried again and it said they are all validated.

-EDIT.
I tried playing and it lasted MUCH longer… but eventually crashed again…
anything else i gotta do?

Remove all the Workshop addons you don’t need, maybe one of them is causing an error that crashes your Garry’s Mod eventually

im pretty sure it`s not the addons, because the crashing started ages after i got the latest one… but i could give it a go and i will update this reply based on the results

-EDIT.
after several attempts to check, the game still crashes. so its not the addons.
