Appimage version in Archlinux only starts the first time after integration

[kde-user]

System: Archlinux KDE/Plasma (CachyOS)

Hello,

I downloaded the electrum-ltc-4.2.2.1-x86_64.Appimage and integrated it into the system using the appimagelauncher ("Integrate and run").
To be honest, I wouldn't know how I could integrate and run appimages manually without the Appimagelauncher.

Electrum-ltc only starts the first time, then no more!

Only if I do NOT integrate it, but only run it once (and do this repeatedly), does it start again.

I have a few Appimages (all integrated into the system using the Appimagelauncher), but this problem only occurs with electrum-ltc.
