All I know is appImageLauncher gave me a lot of issues so as soon as I found an alternative I tried it and haven’t had an issue yet.
You likely ran an outdated version of appimagelauncher.
appimagelauncher for broken for several years when the static appimage runtime came up, the stable release didn't support it. So it would cause people to not be able to launch appimages at all.
It was fixed in the nightly releases but most people had no idea about that.
But anyways appimagelauncher right now does not support DWARFS as well, so it is not able to integrate other appimages. So do not go back to appimagelauncher.
Edit: apparently having an experience gets a downvote. Pretty whiny and weird thing to do.
Just in case it is not me that downvoted you lol
