I've seen this pop up in other places around the forums, but it always seems related to 5500 graphics cards, and we have Radeon Pro Vegas in our systems.  

Across our systems, editors will be playing back a sequence and then the computer just cuts out with the black screen of death.  The weird thing is it isn't consistent across the board - one editor will have this happen at least once a day, while another is just seeing this every so often, while my system has only done it once or twice ever, however we have the same builds and often are working on the same projects.

I've done lots of digging but haven't been able to find any concrete answers, and had IT consultants try to look into conflicts with other software on the computer, but have come up with nothing.  Anyone else have these experiences?   Is it just the bad combination of this particular iMac build + Avid version?  Any help or advice would be greatly appreciated!!!

iMac 3.6Ghz Intel Core i9

Avid NEXIS E4

Avid Media Composer 2019.12.1

Hi, are you still facing this?

Would this be more of a windows issue than an Avid Media Composer related problem?

You've tried different GPU drivers I assume?

Yup still facing the issue.

We are entirely mac based, so shouldn't be anything windows related.  

It is very inconsistent though.  It seems like it's more likely to occur when a person is working in the same project for a whole day as opposed to someone who is switching in between projects throughout the day.

I haven't messed with any drivers at all - not sure that was something you did on a mac system?  Might be in over my head there.
