Unable to Run scenarioBasicOrbit.py Due to vizInterface Error, but OpNav Scenarios Work

[Nyselmech]

I’m encountering an issue with vizInterface when running scenarioBasicOrbit.py. I did a clean installation of Basilisk on my Windows system, and initially, I could successfully run both scenarioBasicOrbit.py and opnav scenarios. However, after a few days, I can no longer run scenarioBasicOrbit.py and now receive the following error message:
D:\Basilisk\examples>python scenarioBasicOrbit.py
Could not find vizInterface when import attempted. Be sure to build BSK with vizInterface support.

Oddly enough, the OpNav scenarios still work fine, and they also utilize vizInterface.
What could cause vizInterface to stop working specifically for scenarioBasicOrbit.py while it continues to work for OpNav scenarios?Thank you for any guidance you can provide!

Odd indeed, I have not seen this before. I would create a new test script where you selectively try to import vizInterface and see if that works, then build out the simulation? You have a script that works, and one that doesn't. This allows you to narrow things down.
