just had a look at the info on my laptop (apple M1 Max chip) system prefs. When i installed the T-Tap a few months ago, it was done using 16.0.2. I had tried 16.2 but it was not working and was recommended to uninstall it and reinstall the earlier version.
It took a bit of mucking about having to uninstall the first attempt before re-installing. I definitely got Flame to work with the TTap but i seem to remember being given a unix command by aja support which was something to do with a bug in Big Sur that caused extensions to not load.
if its any help , the command i was given is sudo /Library/Extensions
i cannot guarantee this is still relevant, and would suggest you try contact aja support and also the flame support to see if they are aware of any conflicts.
I have not used the TTap much as its in my home set-up but haven’t needed to use it for a long while.
