Constant reboots Vero 4K+

My Vero 4K+ is constantly rebooting (due to crashes maybe??) even when not in active use (e.g. while watching cable the tv will suddenly switch to Vero input when it rebooted).

I’ve already done a complete clean install, but the issue persists.

Maybe the power supply is failing?

Hmm, but wouldn’t it then just completely refuse to boot? It stays on for a while, sometimes hours, sometimes minutes.
I unfortunately don’t have a power supply that is compatible to try and confirm/eliminate this as an issue.
