Sign-in window just "spins", is stuck

There must have been an automatic update this week because the application displays "Signed in as <My Name>"; a green, circled check mark, and a spinning circle. The Church background image (of the Saviour) is also displayed, and the version number "V 5.2.10.0". As kmstewar said below, I've been using this for a while. I currently use it in Zoom meetings for hymns, training, and supporting discussion, so my need is urgent as meetings are multiple and weekly.

Thanks for any support you can offer.

So, I posted this two weeks ago (?) Does this mean that the Petawawa Branch is the ONLY unit that is experiencing this problem?

RESOLVED: I have resolved the issue by performing a Reset from the WIN 10 Start Menu (Gospel Library(right-click|More|App Settings(left-click)) Then,
Terminate
Reset
