As per my other thread, reverting back to 7.2.4 has resolve the issue with my Plex Media Server.

Sure, when I attempt to play an TV show or Movie on my TV using Plex Client app, where Plex media server is installed on UnRaid as Docker app, I got long pauses during viewing. The movie would play for about 1 minute, pause (the Plex rotating circle) for about 30 seconds, then play for about 1 min, then pause again ... making it impossible to view a movie on my Plex server. This issue started to happen AFTER upgrading UnRaid from 7.2.4 to 7.2.5.

The solution to downgrade back to 7.2.4 has worked.

So it seems there is some incompatibility issue in 7.2.5 with Plex Media server.

After some testing I was able to resolve the issue:
 
Use TAB key after entering your password.
 
I was using the ENTER key which would not work.

Ok, I believe I’ve managed to discover the issue.  I had installed Unassigned Drive plug-in which seemed ok, but then it showed “reboot” on one of my external HDD USB drives … doesn’t seem to like having two external USB drives … not really sure, but it triggered a reboot grayed out button under the Unassigned Drive list for one external HDD?
 
When that happened (I just noticed now) one of my SSD drives that made up 3 drive Cache (2 SSD and one M.2) disappeared.  AppData is setup to use Cache to Array as well as Media share that is used by Plex (both used by Plex).
 
After 2 weeks of finally getting all my data transferred over to Unraid, I noticed an Unraid update, so let that install this morning and did a reboot … this is when I noticed my cache SSD was set to unassigned and I re-added back to my Cache array.
 
So I suspect Unassigned Drive plug-in “may” have been the source of this.

UPDATE: Looks like the new UEFI now defaults to Secure Boot ... which was enabled.  So I cleared the keys and disabled secure boot and all seems to be working well now.
