Hello GOLD.
This seems like an issue related to the modded content you run.
You can try the following:
Try to verify the game and make sure your mods are up to date
If this does not help - unsubscribe and delete the mods
Delete the game profiles/configuration files
Verify the game data through Steam
Try to launch the game and join a server without mods
Subscribe back to the mods you have had previously

If the issue persists then the issue has to be fixed by the mod creator.
