Crash when opening "system configuration" on mac pro(2019) with 4 or more screens

[wingnut1979]

Am running a 2019 Mac Pro on Monterey (12.1).
I have two Pro Vega II graphics cards installed.
I have six monitors connected (three 5k and three 4k) via usb-c (thunderbolt).
I am able to launch the game and login perfectly fine.
However, if I open "System Configuration" while in game... I instantly crash.
This happens 100% of the time while in that hardware configuration.

Through troubleshooting, I've learned that if I disconnect half of the screens... it all works fine.
Which half is disconnected does not seem to matter.
How the monitors are plugged in does not seem to matter.
As soon as I have 4+ screens connected (and open system config) - the game crashes

Screenshot of my "about this mac" tab alongside the crash error:

Screenshot of the menu item I click to cause the crash:

This one is my normal setup:

2 are connected to GPU1 (1 per bus)
2 are connected to GPU2 (1 per bus)
1 is connected to usb-c port on top of the case
1 is connected to usb-c port on the back (above where the GPUs are)
(Crash)

These are all troubleshooting attempts:

1 connected to GPU1 (with FF running on this screen)
2 connected to GPU2
(Works)

2 connected to GPU2
1 is connected to usb-c port on top of the case

Will happily provide any other info as needed/requested.

Decided to do a little more testing.
I have a 2017 MBP.
I updated it to Monterey and installed the game.
Three external monitors + the built in display:

So it sounds like it's not even the fact that my main one is a Mac Pro or uses two graphics cards.
Four or more screens = death.

@wingnut1979 Could you check if

is properly populated for all your displays?

Might also be a game bug, Square Enix's code is not very robust it also crashes for me with my 10 channel audio interface on Windows or Wine

All 6 are present and accounted for:

One thing of note that I should have stated earlier.
This issue (the crash) does not occur with a standard install of FF.

Fresh update:

Received my new M1Max Studio today.
Connected 4 screens and fired the game up.
Opened system config menu - No crash!

I tried running with a MacBook Pro M1 Max, 3 external monitors and 1 built in display and doesn't seems to crash.
