World of Warcraft using 5000 MBS of RAM

This entire expansion I have had a memory leak and am not sure what other fixes to attempt. I can be idle in the capital city with no addons on after a fresh install and repair and have my game crash. It causes my entire PC to basically freeze.

1 Error I saved but all are similar is DA110F98-B88A-426F-9B77-548F37CFD6D7

I have 16gb of Ram DDR4, Intel i5, 3070 Nvidia GFX card. No other game is causing this. I can run Cata Classic with full addons, weak auras, and live log and be sub 2,500 while raiding.

Would love to enjoy the game without these crashes as they are multiple times a day.
