Hello Ander, Welcome to the Forums.
Try opening up your projects .uproject file in a text editor.
Hopefully you will see the PythonScript plugin listed, you can then disable it by changing ‘true’ to ‘false’
That’s an image of the .uplugin file, I’m referring to the .uproject file that potentially references that plugin.
Digging a bit deeper: It looks like the ‘Python Editor Script Plugin’ is on by default, so it would not be listed in the .uproject file. Also, Fab and Bridge depend on the plugin, so I’m less inclined to disable it.
I did a google search for ‘pywrappermetadata unreal crash’ and came across this thread the use of CJK characters in the filepath might be involved?
