Happened to me today while I was using Chrome and Discord. I noticed something was wrong when everything kept crashing and then saw that Feeds was consuming so much RAM. I've never used all 32 GB of my ram before and this is new. As I'm writing this, my computer has been on for 32 minutes. I built this computer last June and the parts are all new.
Specs:
Windows 10 Education
AMD CPU 5900x
32 GB RAM
Samsung SSD 980 PRO 500 GB as my C: drive (with my system on this one)
Samsung SSD 860 EVO M.2 1 TB as my D: drive
NVIDIA RTX 3090 (I have the latest Geforce Game Ready Driver Installed - Version 512.15)
