Other RAW format works (tested CR2 / RW2), the internal Jpeg preview is shown, but not ARW. It was working right before that. The only other software I found to have the same kind of error is https://gitlab.gnome.org/YaLTeR/identity. STEPS TO REPRODUCE 1. Open an .ARW file with Gwenview OBSERVED RESULT "File loading failed" error message EXPECTED RESULT Internal image Jpeg preview is shown.

Same for me. I guess there is a common library that is buggy ? I can provide ARW file if someone wants to investigate, for my part I have no clue where to search for the source of that issue… 2058872 5 lp.kde 2021-09-05 12:30:10 +0000 *** This bug has been marked as a duplicate of bug 441698 ***
