So, interestingly I was curious about whether 26.7.1 would solve the problem, and...
I forgot that I had a VM running the update process (from 26.6.2).
Interestingly, I got on to my computer this morning and my VM was sitting at at 26.7.1. And is seemingly responsive. My host is also 27.0.1
So, for anybody having this problem, maybe try letting the update process run overnight?
