Game kicks me for "inactivity" 20-30 seconds after i enter a match

Around christmas my game on Ps5 just suddenly started to kick me for "inactivity" while I'm unable to even Change my class. I dont have single Idea why this happens since my Internet Connection is the same as before christmas and other games work totally fine for me. I have since then restored my licence, reinstalled it and checked for issues between the cloud save and the regular one, and while there was discrepancy there after i fixed it it still didnt work. I'm a bit hopeless now...
