2021.3 Video engine and bounce to .mov crashes.

[gives]

OK. Spent a day testing this WHILE I was trying to get approval cuts to my client and director. Finally just sending them audio which works fine for now.
Just a session with movie with movie audio imported bounces fine when selecting a simple 5 sec section in the middle. Always mix bounce from the head of show works at any length.
Went to larger session I am working in with ProRes 422 movie and it crashes with just a simple Eventide EQ or any other PlugIn on. VI's All turned off. I tested eliminating one by one each plugin and then tried to insert just one EQ. CRASHED every time when I was selecting a 5 sec region to Movie bounce.
SO! AGAIN
Got it working with all PlugIns Off in larger session, but as soon as I add just a simple EQ, it crashes again. I added Ozone 9 in and it crashed. I just had Eventide Crush Station Plugin on and it crashed, turned ALL of them off again in the main session and then the movie bounce worked great. However, every plugin I need has to be turned off.
I guess that is what is going on with selecting a region in. A show and trying to bounce it. Otherwise if you do the mix bounce from the head of the show to any length, it seems to work fine with all EQ’s

So, finally I ran down what has been happening-:). I would report this and also I did on the crash report to Avid with each step detailed that I took.

So, resolved for now what is going on with movie bounce mystery-:)
