You have likely left the game file open in the background. It counts time you have the game file open, not actual play time. Steam has no way of knowing if you're actually playing the game or not.

I have no idea how I would've left something like counter-strike 2 running for weeks without some kind of slowdown on my pc

Maybe someone else is using your account?
You could always do the following steps to secure your account if in doubt:

1. Scan for malware https://www.malwarebytes.com/
2. Check that the email and phone number on the Steam account are still yours.
3. Deauthorize all other devices https://steamhost.cn/twofactor/manage
4. Change passwords from a trusted/clean device.
5. Generate new backup codes for your Mobile App https://steamhost.cn/twofactor/manage
6. Revoke the API key https://steamhost.cn/steamcommunity_com/dev/apikey (there should be nothing in the APIKEY)
