I have this issue as well, same versions of everything, and it’s becoming an obnoxious slowdown in workflow. While it’s not game ending, it’s another time consuming step that was initially not necessary.
Hell, this was part of the reason for having PluralEyes to begin with, easily removable audio tracks… and of course the sync feature in CC is a joke.
Did you ever end up figuring out a solution that worked, or did you just give up?
