Apple Vision Pro Crashing at random moments

My Apple Vision Pro keeps crashing with screen going to black at random times. If I do a full restore or OS upgrade it has stability for a few days then starts dropping out again. Resetting settings will also stop it crashing for a while. Apple's support systems are preventing them replacing the unit even though it is confirmed as a hardware fault after multiple visits to the local Apple Store and calls to their online support.

Any ideas on how to resolve whilst Apple works out the glitch in their product repair/replacement system?
