Would you be able to open your search in Windows, type %appdata% and hit enter to bring up the AppData/Roaming folder, then go into the "karasubonk" folder?
There should be a "data.json" folder inside. Would you be able to send that to me privately (Twitter or Discord @typeou, email typeou@typeou.dev) so I can take a look and see if I can find anything that might be causing it?
In the mean time, if you move that file somewhere else, it will reset all your settings but it may also solve the problem. I'd rather you not have to lose your settings if possible, and I'd like to figure out why this happened, and being able to take a look at that file might help with both of those!
