[2019] Game crashing every match for over 10 matches straight when partied with friend. I made a new steam account, bought rocket league on it, played with same friend/computer/download of RL had 0 problems. Why?

This was driving me insane all day.

Since season 12 came out my game has been crashing randomly. I played rocket league all morning and out of about 30 matches it crashed maybe 3 times.

When I partied up with my friend to play ranked on a new account he made, it crashed 5 times out of the 6 matches we tried to play. I could play matches alone just fine but the second i joined into a matched when we were partied up together it crashed every time except one casual match.

I made a new steam account bought RL on it, we partied up and played 24 matches straight and it didnt crash once.

My pc exceeds all hardware requirements and to reiterate the game didnt crash all of season 11 (I've only had the game since about june/july)

Anyone else experience this/hear of anyone else experiencing this?

I have all the log files and crash report files still for reference.
