Mods causing incompatibility with all online games

If I try to host or join any game it will always say its incompatible. apparently, I am using mods that are causing my game to become incompatible. shown here

since its mods related im hoping the modding community would help me find out what is causing the problem. Thank you.

You might want to verify game integrity or delete and reinstall the core data files. No mods installed through steam should be doing that to you if you’re not playing with them enabled, which it doesn’t look like you have.
