SOLVED: Zoom or Webcam freezes in Catalina Opencore 0.6-0.7

Sharing my journey because it appears to affect many people

Specs:

  • Asus Prime z390-p
  • Intel i9-9900k
  • 32gb RAM
  • r590 then 5500xt

Symptoms

When Im on Zoom, my PC would freeze. I can still hear people talk but the screen is frozen.

What I tried:

  • Swapping GPU. Upgraded from r590 to 5500xt
  • Fixed the SMBus using the Dortania guide
  • Upgraded webcam from Logitech 920c to some offbrand (Nexigo?)
  • Plugged webcam into different ports
  • Unplug webcam **This works as a temp solution but I need webcam for meetings**
  • Disconnected my front USB port from motherboard
  • Pulled my Chinese made bluetooth card I got from Aliexpress <== Final solution. This seem to have resolved the problem for me

Note:
Theres a possibility I did the USBMapping wrong
