EX4100 Mapped Drive failure to connect (all of a sudden)

I have several mapped drives and they all seem to have failed since Windows 20H2 update, on this one system.

All maps worked previously but don’t use them on this system much. 3 other systems have no problem connecting, PLEX and app access is still valid from phone/tablet.

I have found a few articles which offer no results.

What other options are there for this issue?
Are there any articles I might have missed?

EX4100 - v5.12.108
Windows 10 Home/Pro - 20H2 (19042.928) (all systems)
