Adobe Dimension Grey Screen

Hi,

I've been using Dimension without issue on an M1 Ultra with 64 cores and now all of a sudden it has reverted to the old grey screen when I add an object.

This used to happen on my older iMac which is understandable and it was purely a graphics issue.

I've tried closing it down and it won't respond. The issue is persisting and hindering my workload for today.

Can anyone advise?

Thanks
