Audio tracks not playing when updating to 2021.6 (Mac OS Mojave)

[jasonfarnham]

HI there-

I'm on Mac OS Mojave. I was working on this song session, however recently I updated to the latest version of Pro Tools: 2021.6. (Yes I know that was already a mistake to update while still in the middle of a session.) And now there's a handful of certain tracks that are just not playing- I have no idea why. The audio files are still there, but there’s no audio- I haven’t changed the output on the individual tracks. ALso on a couple of those tracks, the inserts are also greyed out and not active either. It also seems the bussing configuration on a bunch of tracks are wrong too.

Any suggestions on how to fix this?

How about some system info other than you're on Mojave?
Check to see if any busses have been deactivated in the I/O setup screen.
