Unable to join a lobby or create a server - SOLVED
Okay, guys. The problem of not being able to create a lobby and connect is solved. First, you close the game. Then go through Windows search to %appdata%, then step back to the "AppData" folder and then follow the path to the Local folder. In this folder you delete the "onlyclimbtogether" folder. After that restart the game and everything will work. If the same errors appear - delete the game and delete the folder. Reinstall the game and everything will work in the end.
