"No Audio selected" major AudioSuite bug

[colourednoise]

So I was just editing away minding my own business, suddenly I had this error:




I received it after trying to reverse reverb a clip on my track via an AudioSuite plugin.

I checked all my settings and they look correct:




I then tried restarting pro tools.. nothing changed. I tried ditching my preferences and restarting the machine, but still nothing.

When I attempt to click the reverse button it immediately reverse the clip and then breaks before processing the clip and reversing it back. It also breaks the undo command, I tried CMD+Z to undo the reverse but it skipped back two steps instead.

I am on a work machine, MacBook Pro 15" 2019, 2.6GHz 6-Core i7 with 32GB ram. The OS is Catalina 10.15.6 and we're running Pro Tools 2020.3.0.

The business support for my employer have basically said they can't offer much support other than me sending them the MacBook back, them wiping it and starting again, so I'm holding out for community support instead.
