How to Fix Counter-Strike 2 Won't Launch or Not Loading on PC

fixed my issue thank u so much

My game works when I launch it from the Win64 File location but it doesn't let me join Competitive matches.. I get a message about the Anti-Cheat that reads:
"Some of your game files have been to detected to have no signatures or invalid signatures. You will not be allowed to join VAC secure servers. Please verfiy your launch options, check correctness of your game installation, restart the game and try again." - The game doesn't launch from Steam, even when I try to run it as administrator.

I have uninstalled and reinstalled the game completely and still havwe this issue.

So when I open the game it shows valve logo then just shut down the other day it worked and I didn’t touch my computer the other day

i just cant open the game when i trie to use vulkan

when i check my files of counter strike there is no cs2 application there i think thats my probelm can you tell how to fix that
