I’m just curious how you think this would have happened.
because unless you went out of your way to build appimage luancher or install the nightly releases you would have run into that problem.
That problem was serious enough that we had to add a warning to all of our appimage repos to give you an idea. lsfg-vk even had it happen several times in 2025 💀

And note removing/updating appimage launcher wasn't enough, you also had to reboot, because the thing had a daemon with a binfmt rule that would still prevent you from launching appimages.
In any case you were dismissive in your first message and really negative about software that works fine for me,
I'm very sorry, I thought you were responding to this message about AppManager hence my tone.

AppManager is good.
If you wonder why AppImage had to update the appimage runtime, that is because the static runtime removed the libfuse2 dependency, which was a huge issue appimage had for a long time and to this day I still see people claim this is still a problem. It resulted in that mess with AppImageLauncher unfortunately.
