[GitMensch]

So, were you able to reproduce it (possibly needs the same function to be disassembled)?
If yes, can you please recheck with the current AppImage?

[GitMensch]

ping @Germano0

[Germano0]

hotspot 1.4.80 from appimage does not crash on the specific disassembly line that I use to make crash Fedora's hotspot 1.4.1

[GitMensch]

Let's close this issue then and hope that Hotspot gets an update in the next months and Fedora picks it up soon.
