Just reporting that I'm also having this issue, even after renaming the AppData folder to use a lowercase 'p'. Creating a new palette from current sprite seems to work, the files are created in that AppData folder. But when I open some .gpl files, a quick 'Failed to save palette' message appears briefly. The palettes seem to work as expected, but the files aren't created, and they are no longer available when I open Pixelorama again.

Hello! I think I may have fixed the issue. The fix will be available in the next version (1.0.3), but if you want you can download the nightly version to confirm whether it has indeed been fixed. https://nightly.link/Orama-Interactive/Pixelorama/workflows/dev-desktop-builds/m...
