Not sure about your problem, but I did not encounter any dropouts in W10 until the 2020.5 update, now I get them all the time. I am going to try reverting back to a previous version of CW.
I started with 2020.5, reverted to 2020.4 and did not notice a difference.
I then reverted again to 2020.1. The dropouts "dropped" dramatically from 1 every 5-10 minutes, to 1 every 1-2 hours.
I had made no changes to any settings between versions. Using the same midi tracks with one empty audio track.
Sometimes I would play the project, but the dropout toast would pop up even if it was totally idle and I was on a different window, like a web browser. The toast numbers I got were 0, 1, and 3.
For now, I will stay at 2020.1, at least I can function without getting annoyed.
