Saving the example aas-file not possible

[nofrillsdev]

I wanted to save the example AASX file that is provided in the repo (Example_AAS_ServoDCMotor_21.aasx) in another folder and tinker with it.

But I am unable to save it unmodified in another location - in the log the following entries appear:

Loading new AASX from: C:\x\AasxPackageExplorer\content-for-demo\Example_AAS_ServoDCMotor_21.aasx as auxiliary False ..
AASX C:\x\AasxPackageExplorer\content-for-demo\Example_AAS_ServoDCMotor_21.aasx loaded.

Any ideas what went wrong? I am using the latest version of the explorer (aasx-package-explorer.2024-02-27.alpha) under Win 10 Pro.
