Illustrator 2025 and CEP on macOS = blank panel

Is there anything going on with the macOS, Ai 2025 and CEP?

Can't get my signed extension to run on it. It's showing up in the menu but it's a blank panel.

2024 on macOS works fine; 2024 and 2025 on Windows works fine.

I've been doing extensions for a while now, I don't think I've missed anyting.

After looking into this, I'm not 100% sure but I have a strong suspicion that it has to do with me running macOS on a VM. The logs said something about not being able to initialize "metal", "MTL", so there seem to be a compatibility issue with the GPU in my VM, this only affects Illustrator 2025 so I guess they made som changes in how 2025 render panels.

Unfortunately that's not the problem. I can debug the extension just fine, no errors and all the elements are there. Just that nothing is rendered to the panel.
