Lan-Game

Hello today i discovered a bug that keep happening, after every round i play i cant acces buy menu, everyone apears a zombie and i cant go onto any menus and so on, any suggestions how to fix this?

deliver a standard config if that doesn't help reinstall cs.
unfortunately some servers are damaged by a config and normal game on other servers becomes not possible.

tried reinstalling and removing the whole folder, i dont seem to get the issue since it randomly appeared, didnt happen yesterday and not earlier today, very werid indeed
