Deleting your local profile should help with that.

It will also delete your progress but that SHOULD come back after restarting via the internal cloud save (give it a few minutes).

Just delete everything in this folder:

C:\Users\YOURUSERNAME\AppData\LocalLow\Mighty Coconut\Walkabout Mini Golf\Profiles

Good luck.

I'm having same issues too

Thx Mettanine that solved my Problem.
