A search for those exact words didn't being up studies for me. One of the articles on the first page even talks about the potential dangers. At this point I assume you're teolling swine multiple attempts at asking for studies on real-world data hasn't yielded nothing of value from you. Goodbye.

Apologies, I assumed you'd have to play with the terms a bit, especially with Google being personalized nowadays. For me, the first result on that search is https://www.iihs.org/research-areas/bibliography/ref/2130, which shows about a 16% reduction in backing crash rates. Which could easily conform to the numbers you were showing, as the number of licensed drivers increased by about the same percent. (I'm assuming miles driven and similar would have grown about the same.)

Reading your link appears to be more fear and caution than data showing things are worse? There is a broken link that ostensibly looks at lane assist and how it can have problems in bad weather. But nothing that says rear view cameras actively cause trouble? Just a fair callout that you shouldn't exclusively rely on them.
