Opening projects crashes my computer

[SimonRodgers_UF]

Hello, one and all.

First time poster.

I am having some issues with After Effects and my iMac.

I currently use two iMacs.

One is at work, and the other is at home.

The work one is the space grey model, and the one at home isn’t.

I am having issues with the one at home.

Every time I open After Effects, it completely crashes the Mac.

No error message, nothing, black screen, total wipeout.
I have to force shut down the machine and start again.

I have projects that always open at work that will crash the home machine.

I even tried scaling back one project as it’s quite large, but it still crashed the home machine.

Even if I set up a new project, it will crash.

I thought it might be the RAM, as when I first got this machine, there was only 8GB installed and my work one has 32GB so I updated the machine at home to 32 GB.

After I had updated the RAM, I managed to open a project.

Thinking I had fixed it, I opened another project, and it crashed again.

I got a project to open in safe mode, but then when I started it in normal mode, it crashed again.

This prompted me to reset the preferences, but I think we know where this is going, it crashed again.

I have also seen lots online about AE and Sonoma having problems, but I can’t seem to find anything that matches my issue.

I mainly use Premiere, and so far, it’s only crashed in the same way twice when I have been using Premiere, both times were at the end of the day as well, so I’m not sure if that makes any difference.

The spec for the home one is

Proccesor - 3.6GHz 10Core-Intel Core 198

Graphics - AMD Radeon Pro 5500 XT 8GB

Memory - 32GB 2123 MHz DDR4

Sonoma 14.6.1

After Effects 24.62

Any help or advice would be greatly appreciated.

Thanks in advance.

Do you ever see an Adobe or a Mac OS crash dialog that might have any information for us to review?

Hello.
Thanks for responding to my post.
There is nothing.
The screens go black, and nothing is happening, I have to do a hard restart to get it back working.
It did again today when I was using Premiere, no prompts not spinning wheel, nothing.
Thanks in advance.

Hmm, not sure where to start to help. I suspect something with your GPU hardware is failing, but I would normally expect a MacOS error dialog to appear on restart. Besides Adobe programs, do you have anything else that would utilize the GPU heavily to see if the black screen occurs with other software too?

Because of the issues, I have not been running any other programs while I was testing it.
Just in case.
On the restart, no error messages apart from AE restarting and letting me know that it had crashed.
