Hello, open file explorer, enter"%appdata%" and hit enter. go up one folder level so you're in the appdata folder. Then in one of those "local" folders will be a kyuppin folder. Find that folder and in there is a savedata.uwu backup file. Try renaming that to the regular save data file's name and reopening vtuber kit. But if you've reopened vtuber kit multiple times already, the original save data is most likely gone. I'll have to add an additional backup system or a way to export save files. Sorry about that, I'm not sure what could have caused it and don't think anyone else has reported it.
