cs2 suddenly freezing (only cs2)

Before I start here are the specs:
16gb RAM
i7-13650HX, nvidia 4050

First i'd like to note how every single game runs smoothly with absolutely 0 lag or fps drops.

But when i try playing cs2, first 10 minutes are awesome, 300+ fps and no lag but then all of a sudden for 30 seconds my game freezes and i get 2 fps...

Does anyone know how to solve this issue? I have a really really good gaming laptop that is supposed to handle a game like cs.
I've noticed that when i changed the resolution from 4:3 to native it got a little better but still nothing good.
I've tried playing with the video settings, but still nothing stops the sudden freezes.

I need help.
