Removing installed themes

[nikitsi-a]

Hey,
for some reason the free downloadable themes "Mountains #2", "Mountains #3" don't work for me,
WinDD throws an error notification. I tried overwriting/reimporting them but the issue persists.
How do I remove these specific wallpapers to not get the error in the future? Below is a snippet from the error log file, unfortunately some of it is Finnish as my Windows is but maybe it helps. Win11 by the way.
