Looks like this may be related to the move to Python 3.8 in #10276. My guess is that Jedi isn't working quite right on 3.8 under Windows.

[karthiknadig]

The hover is working on 3.8 with Jedi. it is just the tests that are falling over. For example, the hoverTest.py specifically does this hover (The cursor was on Thread())

[ericsnowcurrently]

Why would the hover work but the tests fail?

FWIW, I took a stab at diagnosing the problem, but ran out of time. I have a PR up to skip the 6 tests and a P1 issue for fixing them.
