iPhone 13 Pro crashing regularly & doesn't allow enough time to back up

I have been experiencing crashes on my iPhone 13 all evening. The screen turns a pink/purple hue and crashes and then reboots itself. It does not stay long enough to allow a software update to see if it would resolve this issue. Additionally, am unable to backup b/c of the crashes. It will only stay on for seconds to a minute at a time.

How do I get this resolved?
