2.9.0. Linux flatpack - No way to select second 'disk'

[mw46d]

Description of the bug

I have an Ubuntu 22.04 laptop with two SSDs. Most of my 3d-models are on the second disk but for whatever reason, the version 2.9.0. does not want to 'see' that disk:-( Even when I try to cd into the directory with all the *.stl files, and try to start with one on the command line, the slicer says 'File not found' :-(
The 2.8.1 AppImage did not have that problem. All the permissions work for the last couple of years ...
I don't know, if that is a feature of the flatpack setup or what's going on ?!

Project file & How to reproduce

File -> Open -> Other Locations -> Computer and my /disk1 is not even listed:-(

marcow@feather7:~$ mount | fgrep ' / '
/dev/nvme1n1p7 on / type ext4 (rw,noatime,nodiratime,discard,errors=remount-ro)
marcow@feather7:~$ mount | fgrep ' /disk1 '
/dev/nvme0n1p1 on /disk1 type ext4 (rw,noatime,nodiratime,discard,errors=remount-ro,stripe=8191,data=ordered)

Please search for existing issues before opening new ones. For example your issue sounds like its the same as either this #13844 or #13820

Both of which appear to be down to the way Flatpack works. You might want to try #13820 (comment) to see if it can resolve your problem.

Thanks. 'Yet Another Permissions System' :-(

@mw46d You can also use this AppImage from this relevant issue

I'm also having problems with the Flatpak and running a post-processing script using Python. I have given all the necessary permissions, but it refuses to run my script. So, I'm just using the AppImage from the link above, and it runs fine now. Thanks to @probonopd for making this possible!
