Audio Silence

I'm having an issue where all the audio just cuts out. I think it may be happening sometimes when I minimise Resolve and when I maximise it the audio may or may not function. I have to restart. Few other audio glitches too.

M1 Mac - Beta 20

Is this behaviour on the Edit page or the Fairlight Timeline?

What is the current configuration in Resolve Preferences > System > Video and Audio IO?

What is the current block size?
Resolve Preferences > System > Video and Audio IO > Playback processing buffer size
