2014 Prius V not starting and making noise near inverter coolant

seeking help to troubleshoot my 2014 Prius V (station wagon). It has about 120,000 miles and I’ve done all the maintenance on it regularly. For few weeks, it wasn’t starting all the time. I’d push start and all the dash would light up and I’d just try it again and I would hear a faint click in the rear and I knew it would start. Fast forward yesterday, it would not start at all, and I recorded making this noise. It’s the noise you hear as soon a as you enter the car with the key but it sounded like it was dying.

I pulled out my techstream and ran but I didn’t get any code. When I push the start button twice without having my foot on the brake, I’d only see the check engine light and that annoying noise. I’m attaching it. Any ideas what it could be? Inverter pump? Or fuel pump? Will be uploading video link shortly.
