MCC lagging, CPU usage 100%, single digit frames

Games Halo: The Master Chief Collection
1

Basically the title. MCC on PC didn’t do this until recently. 2-3 weeks recent. Any time I play MCC, I get moments of massive stuttering and lag, followed by 100% CPU usage. Frames drop into the single digits. This only happens in the main menu, multiplayer or Firefight. Not during Co-Op campaign with a friend who is from Europe(Me being in the USA).
My PC can go for a while before needing to be restarted, but any time I launch MCC, it’s hardly a day before other apps and programs on my PC take a nosedive. My PC is more than well equipped to handle MCC with no issue.
Any ideas as to what’s going on?

Forgot to mention: I also frequently experience an issue where my audio gets crackly. Any music or audio from Discord is immediately affected as well. When I exit MCC, the problem goes away. I have to unplug my Wireless Headphones base to get the issue to subside.
