Multiple cylinder misfires on 2013 car seemingly out of nowhere? What to look for?

Summary: Sudden bad idle, CEL light, multiple misfire codes

41k miles car.
Recently: Alternator went toast, was replaced with a new OEM unit along with all new 8 intake manifold gaskets. A new air filter was also installed. Seems like the car was put in better condition than it was. Was running great. No more battery light. Alternator putting out correct charging. So that's fixed.

3 days later ... drove it to my mom's for Mother's Day....seemed to drive fine. Hours later, I try to leave, after starting it up....it sounds and feels bad. Like cam loped (but a really bad sounding ..)and car shaking like a 9.0 earthquake. Seconds later I get dash beeping warnings and flashing CEL lights.....of course..something was obviously wrong.
..did not drive it but a little to put it in their garage since I wasn't going to try and drive it home.

I will attach an image of the codes I scanned, but it's P050B, P0571, P0301, P0308, P0307, P0305, P0300

The intake seems to be on fine? If there was a vacuum leak after fixing the alternator surely it would have been noticeable immediately ??

I will take it to a shop, but I would like to know what possibilities this could be for my own general knowledge ? Since it is affecting cylinders on both sides of the engine. I have had varying input from techs and racecar mechanics I know, but wondering opinions from people on here as well who might have some thoughts.

It just seems so immediate. Some people are swearing it's spark plugs but seriously? Do 4 go bad all at the same time?.That just does not seem right at all and yet multiple Ferrari owners have this same story and the fix was just plugs?? If plugs foul that badly that quickly is there not surely an underlying issue then too ? I can check them and wouldn't mind replacing them and maybe the coils. I just doubt highly that is the issue.........it would be nice if it was.....however.....easier than other issues....such a sudden change, wouldn't we assume some electrical components??

Thanks for any thoughts. It's not my daily driver so I am not in a panic over it.
