Thanks for reporting!
If you have time, would you be able to open CMD and copy paste: "D:\Files\Games\AI Roguelite 2D\AI-Roguelite-2D-1\tools\magick.exe" convert "C:/Users/mfrkl/AppData/LocalLow/MaxLoh/AI Roguelite 2D\saved-world-infos\84d5c775-1749-491f-b6f6-116081b5c2b4\images\c08e660e-a2a2-4a0d-8eb7-064eb650c17d.jpg" "C:/Users/mfrkl/AppData/LocalLow/MaxLoh/AI Roguelite 2D\saved-world-infos\84d5c775-1749-491f-b6f6-116081b5c2b4\images\c08e660e-a2a2-4a0d-8eb7-064eb650c17d_mask.png" -alpha Off -compose CopyOpacity -composite "C:/Users/mfrkl/AppData/LocalLow/MaxLoh/AI Roguelite 2D\saved-world-infos\84d5c775-1749-491f-b6f6-116081b5c2b4\images\c08e660e-a2a2-4a0d-8eb7-064eb650c17d_removedbg.png"
And see what it says?
Also, if you could give me the entire Player.log, that would help me figure out whether it was a specific image that caused it, or imagemagick was never able to run
