Have you tried with addons disabled and turn them on one by one?

In my case there were several addons causing this behavior and I'll wait a few days in hope the addon creators manage to solve it because I not familiar with LUA programming language.

Do you use Auto Category?
It seems this addon is causing this issue as reported by several users at esoui.

If you choose to use addons, and if the addons you've chosen to use are causing issues with the game, then IMHO that is not on ZOS, but is squarely on you and the authors of the addons. Addon authors should thoroughly test their addons on the PTS before a major update goes live, so they can find and fix any issues with their addons. And players who choose to use addons should update all of their addons after a major update goes live, and if they've done that but still experience issues then they should disable all of their addons to see if the issue goes away, then reenable their addons one by one-- or in batches of a few at a time if they've got a lot of addons-- to see if they can determine which addon is causing problems.

It's exactly the same with single-player TES games that have been out for years-- players who choose to use third-party mods and addons with those games should not blame Bethesda if all of those mods and addons cause problems with the game, and it's on them to try to figure out what's causing the problem and look for a solution.

If ZOS wants to allow the development and use of third-party addons with ESO, that is a commendable decision and is much appreciated by the players who enjoy using addons (of whom I am not one, but that's just my own preference). But that does not put any responsibility on ZOS to test every third-party addon that's out there, or make changes to their changes if some random addon can't handle the changes and the author isn't even maintaining their addons any more. The responsibility lies squarely on the shoulders of the addon authors and the players who choose to use those addons.
