Python error on startup

[eflaten]

The error is reported her:
qgis/QGIS#57996

[eflaten]

Just to mention the error is still there in version 3.8.1
However, when starting up the conda-buildt version of 3.8.1, QGIS starts fine.
There might be several diferences between the macos installer, the one that gives the python error, and the conda way of installing. I could see one. Its python 3.11 on the readymade installer and 3.12 in the conda buildt version. Hope this helps :)

Under is the python error from the macos installer.

I get the same error. QGIS does start up fine. But, I am running a script in the Python console and it is throwing a new error I didn't see in 3.36. See #22.
