Adding to Matt's list:

Was there a Win 10 update recently?

{Edit} - Some updates have been known to mess up audio drivers. Most of the time a driver reinstall will fix the problem.

My wife is so thoughtful why just last night I woke up to find her putting a pillow over my head so I wouldn't get the coronavirus!

64 bit Win 10 Pro, the latest BiaB and RB, Roland Octa-Capture audio interface, a ton of software and some hardware.
