n00b error running lldb tests on windows?

Hi,

I’m trying to run the lldb tests on Windows (fresh installs of VS2019 16.7.5, Python 3.8.5, and Swig 4.0.2). The API tests crash immediately in python initialization code:

Windows fatal exception: access violation

Current thread 0x0000693c (most recent call first):

Running in the debugger, I see “_PyRuntime.gc.generation0 was nullptr”.

I presume I have something set up incorrectly in my environment, but I haven’t had much luck figuring out what. Is this by any chance an error/stack that somebody recognizes as a common/known issue?

Thanks,
