Qt error with Python 3.8.8 on MacOS 11.6

[joebathelt]

A recent update to some software broke PySurfer for me. After initialising with 'ipython --pylab qt' and running 'from surfer import Brain', I get an error that reads:

Qt WebEngine seems to be initialized from a plugin. Please set Qt::AA_ShareOpenGLContexts using QCoreApplication::setAttribute before constructing QGuiApplication.

Afterwards, it just hangs indefinitely. Here are the software details:

PySurfer: latest Github version commit: f02cca8
Qt: 6.1.3
Python: 3.8.8
OS: MacOS 11.6

Any help would be appreciated!
