Intermittent error lights (triangle and hybrid system)engine code 2007 Prius

We initially got the red triangle, check engine, and hybrid system error light (from the secondary display on the touch screen, images attached). We let it sit a bit and when I went to take a pic of the error lights and to try to move it a short distance, the gas pedal wouldn't "engage", no flow from gas engine to charge the hybrid battery which was on the lowest bar, so parked the car immediately.
After a couple of days we tried a little trouble shooting including checking inverter coolant pump, the error lights were not coming on at that time.
So my husband ordered a FIXD reader, which is generating only a P3190 - Poor engine power error code.
The 12V battery has previously been replaced once but has been a few years.
The main hybrid battery is a replacement refurbished battery 2-3 years old.
Another note is this all happened just after we'd had some work done after putting new tires on and having vibrations....the shop fixed the struts in both front wheels.
Looking for any thoughts on what the problem might be?

Thanks for the response.
It has just under 200k miles. Currently that car (just pre the issues) was only being driven probably a day or two for short trips every couple of weeks, given COVID and wfh.
I think I've seen on here a way to check the voltage? I'll have to see if can get ahold of a voltmeter but that hasn't been checked yet.
The car was driven after the strut work (well, after the tires, but it was brought home then down to a different shop, tires were put on at BJs) back to the house. I'm pretty certain the next time it was driven was a short trip in the neighborhood when it triggered the error lights. So it's possible my husband didn't notice the battery wasn't recharging on the way home from the shop. There was a brief time where the gas wasn't charging the battery, but it apparently did some yesterday. We haven't done more than really short trips moving it around during trouble shooting as didn't want to do more damage without having a better idea what we may be looking at.
Thanks for the information as well!
