Player won't play lesson

[MarkHulbig]

In UFMBP-App ->Assignments _-> Marking and Clipping Queens

Click on the play button, icon changes to "pause" but the player does not play/advance.

Was working on previous lessons. 

Chrome Browser, Windows 11.  Restarted browser, rebooted, still no luck.

Tried Edge also, does not play the lesson.

The issue was a bad USB hub driver after Windows update.

Uninstalled the driver to previous version and player works.
