Sourcemods SEVERE Lag and Hardcrash after 5 minutes

Originally asked on reddit, got downvoted LOL

No matter which mod I play on, I get sub 30 fps, and lag spikes every 2 seconds. Then after 5 minutes I get a hard crash. No matter the mod its the same amount of time they crash. Why does this happen and how do I fix this, this is bullcrap.
Edit: Forgot to mention this doesn't happen in the main game only in sourcemods

Sourcemods tested:
Portal Origins
Mind Escape
Portal Lunar (Just crashes when opening console)
Portal 2 Memories

for some reason the same thing is happening to me after the update even on vanilla

The only thing i can think of is this:
are you currently subscribed to a lot of workshop maps?

Portal 2 will start to download all of them into each sourcemod folder and consequently reduce performance and run out of memory (crash).

Switching to offline mode in Steam before launching the sourcemod prevents this.
Or you could just unsubscribe from all your subscriptions in the portal 2 workshop.

Thank you so much, it works like a charm now :D

I have a similar issue, but with normal Portal 2. The game, however, runs 300 fps easily. But randomly it will hard crash my entire computer after 5-30 minutes. I have had this issue for 5 years and I can't find a solution, any ideas?
