Hello everyone!
I've opened up FreeCAD today and was met with a error:
During initialization the error "libshiboken6.abi3.so.6.9: cannot open shared object file: No such file or directory" occurred in /usr/lib/freecad/Mod AddonManager/InitGui.py
This never occurred before and disactivated the plugin manager and all my plugins!
I've already installed the newest `shiboken6` package and I've tried to search for the lib online and via `pacman -F libshiboken6.abi3.so.6.9` but I found nothing so far
Does anyone know what caused this/which package has this lib? Thanks!

Yep, I've updated my system and nothing changed :c I'm sure that I don't have a partial upgrade too

Does FreeCAD work if you remove all mods? Looks like it's either a mod or the "AddonManager" that's causing the problem.

Problem is that I cannot remove all the addons without the addon manager. Plus the AddonManager is a built-in feature of FreeCAD

A quick search suggests that user mods are installed under ~/.local/share/FreeCAD. Try moving that directory or some of it's contents elsewhere.

How did you install FreeCAD? Post the output of
pacman -Qikk freecad

Just tried that! But nothing changed unfortunately. The same errors still pop up

How about `pacman -Q pyside6 shiboken6 python` and `type -a python python3`
Offline
If Scimmia's suggestion does not turn up any leads I would suggest `type -a FreeCAD` `LD_DEBUG=files FreeCAD` and if that fails to produce any additional output `strace -f --trace=%file FreeCAD`

Thanks a ton for the lead loqs! I've found the error now:
Turns out that there was an additional pyside6 installation at `/home/cyao/.local/lib/python3.13/site-packages/PySide6`, deleting that directory worked I have no idea how an user python package got installed lol.
