I haven’t tried the conversion yet (as my game is set up for my re-write), but try deleting or moving your “progress data“. This sounds like the common error with heavy mods. Saves will show blank afterward, but they should load correctly afterwards and then show correctly upon the next save (if it’s that error).
I would recommend backing up your save data first. If you’re unfamiliar, it’ll be under the Strive folder in your App Data (around where you installed the mod).
