Crazing banging noise but goes away when in reverse

How it all started, my car burns a little oil. My mom was driving it and it started to lose power and stutter without any banging. She drove a little bit and pulled over in a parking lot. Then she checked the oil and it was low so she added w20-50 conventional. She tried to start it and it started banging she called me again told me she had put 20-50, I went over there and changed the oil myself right away in the parking lot and put 0w-20 synthetic. Tried It was still banging and shaking the engine violently. Towed it home and left it for the night. It still makes a really loud banging noise but does go away when I go in reverse. (Please check videos) only 15 seconds each.

Things to note:
1. The banging noise is significantly decreased when I drive in reverse.
2. the last oil change before this one was not done by me but by a shop.
3.The hybrid battery has been giving me trouble and the light comes on but I unplug the 12 volt and plug it back and it works fine, just squeezing that last bit of life out of it before I replace it. The code is “change battery pack”
4. I did get a recall letter about two days ago for a software update that might burn the inverter, I doubt they’re related in any way.

1. Loud noise (without putting it in reverse)

2. When I put it in reverse

3. First start up in the next morning

Here’s my theory, the oil was low and it needed to be topped off but the extremely thick 20-50 oil is still stuck in the engine not letting the 0-20 flow properly.
Thank you all very much!
