I checked our AppImage using appimagelint as described here and it does not find any blocking issue with it.
For now, I would suggest to run the AppImage without AppImageLauncher or by using the "Run once" button.
If you have any idea on how to solve this issue, please post it here, or submit a PR and we would gladly review it.

I have the same problem with kDrive-3.6.0.20240521-amd64_b0a75b1ea1feba09158ff886b7c253da.AppImage on Kubuntu 22.04 LTS with AppImagelauncher.
Seems to run OK with "Run once".

Not really helpful, but I can confirm that this is working on Ubuntu 24.04 (current LTS).

@smiddy Is the workaround suggested by @ClementKunz a satisfying solution?
