Description: I click the join lobby button for Killer or for Survivor, and it will start searching for a lobby. After a bit(maybe 15 seconds), the screen first goes to the black background with DbD logo loading screen, then very shortly(about a second) I get put back to the opening screen when you start the game(Press space to continue). However, it also has a message(screenshot above) saying "Your session has expired. Please sign in."
Replication: I wouldn't know.
How often: This started happening approximately one week ago. I have tried Survivor and Killer almost every day, with the same results each time.

Troubleshooting: I have tried all the troubleshooting I could think. Uninstall+Reinstall the game, verify local files, go to forums to search for other users with the same issue(only one person found) - I even tried doing what it told me to do - Sign out of Steam then sign back in. None of those did anything at all.

I still have this issue as of update 3.4.1
For the record, your log says this is your GPU.
The only thing I can think of, which I am absolutely going to admit is a bit of a hail mary guess, is that your username might be too long. Try shortening it in steam and see if it resolves the issue.
