AppImages after 7.5.0 aren't launching.
When trying to run FLC v7.7.0 (via AppImageLauncher), on Fedora Linux 41, and selecting Integrate and run, it gives the error: "Failed to register AppImage in system via libappimage." When selecting Run once, nothing happens.
I tried doing it thru the terminal and, in case it helps, these were spit out: Integrate and run

execv error: No such file or directory
My many other AppImages work. I looked up the error I got when attempting launching/integrating, and found this thread about a different app.
Just in case, I tried installing each previous version until one worked. I had to get to 7.5.0 before it would launch but, in that case, the app is a blank white page.
Just checked 7.8.0 on Omarchy (Arch Linux) and it works fine.
I updated to 7.8.0 and 7.8.1. Like, 7.5.0, they now launch, but are blank.
Given that AppImages should just work, regardless of distro, I'm not sure what the problem is. I also tried 7.8.1 on Fedora COSMIC Atomic (Fedora 43 beta), and I had the same issue w/ it launching but being blank.
Try to clear the cache: Open FLC -> F12 -> Application -> Storage -> Clear site data
It doesn't seem to be able to receive keyboard inputs. The window just looks like this. In COSMIC Atomic, it looks the same, but replace the white with a dark grey.
