I can't open the character bios and I'm too stupid to understand Ren'Py :(
This usually only happens if you're using a save that was made prior to 0.22. However, once the 0.22 content starts (At the start of day 11) it will fix itself. If this describes your situation, then you'll either need to basically just not use the character profile screen until the morning of day 11, or start a new save.
