Upload an asset not working

Using Endeavour OS and logseq is Logseq-linux-x64-0.7.7.AppImage.

When trying Upload an asset a windows pops up where I am supposed to choose the asset.

However, the window does not respond to any mouse click. Keyboard is only working to select a directory with the TAB key. No possibility to switch to the right side to select a file.

Is there a way to debug this?

I just want to add that on a RedHat 8.5 system Upload an asset doesn’t work the same way.
