OBS and Mac fail to shutdown cleanly - debug/fix assistance requested

[FrankReality]

Experiencing a plethora of shutdown/exit issues on OBS and MacOS and need assistance to determine how to fix.

Several suggestions have not helped;
-- removing unused/outdated plugins
-- updating the necessary plugins
-- downgrading back to v29 OBS

Today's session:

1) Upon boot Mac laptop reported a crash - was sent to Apple - included here because relatively small

2) Started OBS - checking scenes for recurrence of a past problem, NDI is now working
Nothing unusual/unexpected found in OBS log, so exited OBS.

3) Another Mac problem reported - sent to Apple - relatively short dump so included here

4) Restarted OBS, captured current OBS log - nothing obviously wrong there - uploaded as https://obsproject.com/logs/oTORslUNt9gqhRPR

5) Reviewed previous OBS log - shutdown crash - uploaded as https://obsproject.com/logs/B5KO5R1Nm5eptEtl

6) Started recording, streaming, stop streaming, end recording, reviewed the current log again
No major problems in log other than the normal error decoding video errors. Apparently from an iPad used as a camera.

7) Exited OBS - got the infamous "OBS Studio quit unexpectedly" box
Sent to Apple and posted to https://pastebin.com/RYKL2JeE

8) Restarted OBS grabbed previous log - uploaded as https://obsproject.com/logs/OQzfvQRzTgLGKSKB
(Excerpt of log - nothing after killing NDI)

Actually figured this out myself - here's what worked for my instance of this problem. Your mileage may vary...

Close the YouTube Live Control Panel dock via the red x in its upper left corner before you shutdown OBS.

That's it.
