Zoom room freezes on Audio echo test

[carlson1]

We've had a Zoom room on a PC setup for some time, and every few weeks it will freeze up at the exact same time (2:51 AM) running the "audio echo test".  This freezes the whole PC, so the only solution is to hard power down the system, then back on.

Is there a fix for this?  What could possibly cause this to happen?

Thanks in advance
