Could you try deleting the MyProject folder, and see if that solves the issue? The game should just create a new one if there isn't one present.
In theory, that folder contains files for a script to keep game's options (like "always dashing") separated from the save files, but the script caused a couple of issues lately, so I am also considering removing it. Let me know if this workaround solves the problem, I'll try to figure out why it behaves differently between the two version.
