SOLVED: JF Media Client on Win 10 changes versions, inaccessible if run as standard user

[ninefootnails]

Encountering a version issue and general functionality with a windows 10 media player installation.

Server is in a docker container on a Ugreen NAS, v.10.10.3
Media player (1.11.1 x64) is on PC, Win 10

Previously was on server 10.9.11, Win 10 media player (1.11.1 x64) installation working great, ran as standard user without issue.  

After rebuilding the docker image a couple days ago (because an android Jellyfin TV app requested I update the server to the newest version) I noticed when I open the media player on my win 10 pc that I couldn't click into any libraries.  Closed and reopened, rebooted, many times each, never could access libraries, but randomly was able to click the menu and see the dashboard.  I noticed that the versions didn't match in the media player, it listed the following:

Server Name: UGREENNAS
Server version: 10.10.3
Web version: 10.9.11
Build version: 10.9.11

I decided to try repairing the install through the add/remove programs control panel and it returned a successful repair message.  Launched the application and libraries worked, dashboard showed the following:

Server Name: UGREENNAS
Server version: 10.10.3
Web version: 10.10.3
Build version: 10.10.3

Closed app and reopened and it reverts to the incorrect version listed, and libraries are not able to be accessed (main screen shows libraries, everything looks completely normal, mouse clicks just don't do anything).  After some more uninstalls, reinstalls, install locations (c:\users\USER rather than c:\programfiles) I cannot get the program to work when launched by a standard user without first performing an install repair, and then it only works once, the fix is not persistent.  If I launch the program as administrator it works, shows the proper versions, and has no issue.

I believe this is a problem on the windows side of things, like some scrap that didn't get cleaned up when the program is uninstalled or repaired and when launched as a standard user it's using some old programdata or something, I'm just not sure where to look.  After each install the media player never asked where to find the server, it always just knew, I don't recall if this is normal, but I did expect to have to point it to the correct network address but never was prompted after any new install.

If anyone can review and help troubleshoot this I would appreciate it.  Thanks in advance everyone. Please let me know if you'd like any additional info.

Go to C:\Users\yourUser\appdata\local, delete both the "jellyfinmediaplayer" and "Jellyfin Media Player" folders. In a browser, go to your jellyfin server and then Dashboard > Devices. Delete all the tokens for Jellyfin Media Player.

Open Jellyfin Media Player and log back in.

That was the perfect remedy and I learned something today.  Thank you TheDreadPirate for your help!  Very much appreciated!
