Problems with saving in docker container

[QuiriniusvonBayern]

Hi, I don't know if this belongs here or under issues. If I am wrong here I will create an issue.

I'm using Isaac Sim 2023.1.1
ROS2 humble
Orbit IsaacLab-0.3.1

I am trying to run the repository in a docker container, build from the dockerfile and entrypoint script I attached.
dockerfile.txt
entrypoint.txt
(there were other problems I was able to fix myself. The files are a bit messy).

This works fine except for a couple of issues:
When I start the simulation, I get the output in the first text file and the simulation runs without obvious problems.
Output_1.txt

When I try to do any of the actions from the 'File' menu (like save, open...) the simulation stops with this output:
"[443.621s] Simulation stopped. The application will continue to run with physics disabled. Press Ctrl+C or close the window to exit the application".

From this point on, the simulation cannot be restarted and I cannot open a save of the scene. When I try to restart the simulation I get this error and then the second one when I try again.
Output_2.txt
Output_3.txt

When I save the scene (with the simulation stopped) and load it, I get a lot of the same errors as in this file:
output_4.txt

All actions in the "File" menu cause some kind of error. Isaac Sim and Orbit run fine in the container and I can save without problems.
