I should reiterate though that this bug is preventing me from getting past the title screen so the game is totally broken for me at the moment.
Try going into your Steam directory, finding the Desktop Dungeons folder, then DesktopDungeons_Data -> Saves -> long number -> <name of your profile> and move all the run files out of there. Hopefully that should still keep your progress in terms of unlocking things, but remove any run data so you'll have to finish dungeons again once or twice.
If that doesn't help, backup everything in your saves folder before clearing it out entirely. That will reset your progress completely.
