It does happen randomly (it seems), feels like the sort of thing that happens when the power momentarily cuts out, but the picture does freeze for a few seconds before it crashes.
Might there be a log file or logging option that I could turn on to capture it “live”?
You can get a bug report from Settings 》Device Preferences 》 Developer Options 》 Take Bug Report. However, there will not be any useful information because it cannot be written to the bug report as the system crashed! Bug reports work when an app crashes.
