Mic develops an echo only when sharing (I think new Windows 21H2 update broke virtual cables w/Zoom)
Currently having issues with my microphone, receiving audio into Zoom that came via Virtual Audio Cable, but only when sharing something with sound enabled. The mic works just fine when not sharing. It also works fine if I do not use a Virtual Audio Cable / OBS Studio. Unfortunately, I need the OBS and Virtual Cable to add exciting effects for my classes -- running Zoom just plain-jane is workable, but not the end goal. I will note that my entire set-up works just fine on another computer at home, and has for a year.
See video here, and pay attention to what happens when I share:

I think the recent Window update may have messed things up with my virtual audio cable and how Zoom "hears" it, but only while I share? This problem does NOT happen if I simply go directly from my mic into Zoom. It only happens when I route through a VB Cable (or Voicemeeter Banana). All diagnostics for the VB audio products are clean, with OK driver test results.
Currently, my setup is a behringer mixer with mic into the computer via USB. I am feeding that directly into OBS Studio. I send that out via VB Audio Cable A Input, then use the VB Audio Cable A Output into Zoom's Mic. Zoom's Output is to my headphones. (Note: I've used other programs, like VoiceMeeter Banana to feed the audio, and same echo problem occurs in share, so it's not an OBS settings problem).
So I'm at my wits end as to why I am getting echo when sharing? I'm running the same set-up on a different computer at home, and no problems.
This problem situation is happening on a Windows 10 21H2 updated Asus notebook.
