@mostlostnoob I don't know what I did, but it worked. Thanks for your help.

@mostlostnoob Nothing helped. When I close this error, I am redirected to a site where I need to log in, and then I need to attach my Steam account, but it has already blocked me, and I don’t know what to do next.

Today I installed the launcher and when I launch it I can’t log in, and I get this message.
