Hello ElvisKing,
Moved the thread to the proper forum, and at this forum here, please read the sticky posts at the top as they explain how to find your correct addon folder (Screenshot trick e.g.) and what can interfere (OneDrive, etc.).
Thank you

Edit:
It sounds like AntiVirus or other tools block access to your c:\users\windows user\documents\elder scrolls online files!
As you said nothing saves.
Add this folder to your AntiVirus "allowed" list (or "exclusion" list) so it can be access properly by your eso64.exe file (Game's executable).
Also add the game's executable to the allowed list so it is able to operate properly and is not blocked by your antivirus/anti malware tools!
As settings and "did I acknowledge to use addons and did I accept the disclaimer" gets saved at c:\users\windows user\documents\elder scrolls online\UserSettings.txt and enabled addons at AddOnSettings.txt
After that:
At the AddOn manager ingame: Do you see any addon there? Do you see a "Disclaimer" keybind at the bottom right? Press it, and acknowledge it to enable addons then
