I also used the 128x128 PNG icon from the Resources folder…
libfuse2 is already the newest version (2.9.9-6+b1).
Really appreciate your help

I’ll try spinning up a VM tonight with Debian 12 XFCE and see if I can replicate the issue.
Also if you could put one of your successful failure Appimages into that drive link you shared, I’ll look inside it for issues.
