Problem with bootlooping console

Hi everyone. I've been looking around for solutions to this issue for a while and haven't found anything conclusive. Basically, nearly every single time I start my car, the screen will turn on black, then the Toyota logo, then *maybe* a fraction of a second of the Bluetooth connection screen (or backup camera, basically whatever was/is active), and then it will repeat.

This has been going on for over a year now. I previously asked my Toyota dealership about this, and their only answer was to diagnose the issue for $85/hour, which just seems insane to me. I'm getting ready to go in for my 50k maintenance, but wanted to see what other options people might have for me before I spend what might be a lot of money on a maybe, you know?

 

Reasonably sure that I had the battery replaced somewhere between 3.5-5 years, which would mean this one is less than 2 years old at worst. The dealership flat out said they can't do anything about the console when I come in an referred me to a 3rd party, so maybe they can at least tell the health of the battery as a starting point.

e: Would it still be the battery if the car has been fine otherwise and this problem has been going on for a year+?
