Fix in:

https://github.com/audacity/audacity/commit/21296b0

Seems to work fine, but I need Paul's with setting up an exception to exit Audacity a bit more gently.

Tested on W10 with Audacity 3.0.0 21296b0

This now works properly on Windows, with
a) an improved message
b) help button in the message
c) no launch of the Plug-in Manager while the problem remains
d) fixing the problem by unlocking and then using the Retry button proceeds to launch the Plug-in Manager
e) the Quit Audacity button - "does what it says on the tin"
