Proper tree crash on BigSur

Hi everyone

Propertree worked flawlessly in my Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina OpenCore 0.6.3 but since I upgraded my rig to vanilla Big Sur OC0.6.3, Propertree never worked anymore. Every time I run it, a window appears with a looooong list of texts shows where it got fault, and it seems to relates to the Python verion/core

please tell me what should I do to fix that annoying thing. Any help is highly appreciated.

Have a nice day.
