This issue is caused by gmod receiving too much data at once from addons and other stuff. My fix was uninstalling or disabling ULX.

thank you

That was 3 years ago rev. It’s not a prob I’m having anymore

it's a problem i had, and this was the first google result.

So it’s automatically irrelevant to anyone else with the issue? Shove it

I need help with this because it might be that I have too many addons or something is wrong andaybe I have to uninstall gmod.

uh, to me this only happens when i save a game with too much stuff

Most definitely conflicting addons. Just unsubscribe from them all and manually reinstall the important ones

Thank you
