Application freezes when opening a document

[wohltat]

I compiled FreeCAD according to the instructions using the container approach from the freshly cloned repo. It seemed to be be successful but if i try to open an existing or a new document the application freezes with following error in the terminal:

> ./freecad.sh --verbose

I used maybe an old container. I repeated everything and now there is a different error but the same freeze:

>>> ./freecad.sh --verbose                                                                                                             ‹git:master ✔› 16:27.59 Thu Apr 06 2023 >>>

Maybe something changed with the FreeCAD code. I'm on it ASAP.
