Problems creating a profile!!!

An error began to appear when creating a profile or loading a new map (EXC NullReferenceException: Object reference not set to instance of an object). Solving the problem on your own is not possible. Deleting all the game folders, changing the version of the game, as well as reinstalling windows 10, did not fix the problem. Before alpha version 20.4(B42), everything worked fine. I can't understand the problem. Please, help!!!
