What is the issue you’re having?

Hey, for the last few days I have had a problem with FiveM crashing. Anyone know what might be the reason?

What have you tried already to fix the issue?

I did fresh install of FiveM and GTA V. When it want to crash it drops fps to 1-10 and whole PC starts lagging.

What server did you get this issue on?
