Sounds good, I've signed up for the beta. The issues I've seen with Big Sur and the Tinkerine Studio revolves around OpenGL. Can bypass some of the initial issues brought up by updated/lack of OpenGL. I've edited the Resources/lib/python2.7/OpenGL/platform/ctypesloader.py and updated fullName var:

fullName = None

try:

# fullName = util.find_library( name )

fullName = '/System/Library/Frameworks/OpenGL.framework/OpenGL'

This gets me a bit farther, however, now hitting the following:

No handlers could be found for logger "OpenGL.arrays.arraydatatype"
