TypeError: in method 'VizInterface_spiceInMsgs_set'

I have successfully built Basilisk. When trying to run scenarioBasicOrbit.py, I get the following error

Traceback (most recent call last):
File "<path2bsk>\src\examples\scenarioBasicOrbit.py", line 567, in <module>

By commenting out line 398 of scenarioBasicOrbit.py, the code runs fine, but I would like to use Vizard as well. I have tried on both Mac and Windows, on version 2.2.0, 2.2.1, and the newest version to date. When building, --vizInterface was set to True by default.

Did you install SWIG 4.2? If so we're seeing an issue with it which is being worked on but a solution might be a few weeks out from a release. You can try installing SWIG 4.1.1 instead.

Thank you! This was the problem :)

I seems to have gotten the exact same problem, so I downgraded the swig version to 4.1.1 and it didn't solve the problem. Does someone have any idea?
