Bug: Share computer audio cannot be selected

[AirtightEng]

When I try to share my computer audio during a meeting, I can click on the "share computer audio" option while sharing my screen, however no check box appears to indicate that my computer audio has been shared. This was never an issue until a few months ago when Zoom installed a software update.  I have not changed my process at all, and yet I can't seem to get it working. I'm running a PC and sharing audit for Youtube videos. Any help?
