As described there (and also described here "lua error messages ingame - How do I read them?"
https://www.esoui.com/forums/showthread.php?t=8858) report errors at the addon / library comments.
The error message says "LibHistoire" so the error is somehow related to that library:

Often you find similar errors already reported there, and maybe even a fix or someone describing what you can do.
Only a guess how to maybe fix it:
Logout.
Go to your SavedVariables folder (described here how to find it:
https://www.esoui.com/forums/showthread.php?t=9235)
Backup the file LibHistoire.lua
Rename the file LibHistoire.lua to LibHistoire_20240523.lua
Login and see if the error still occurs.
-> Attention: You need to setup your LibHistoire UI settings new, and for example define the categories you want to sync, per guild, at the LibHistoire UI at the guild history again - Via that small "gear" icons at each guild's category. e.g. set the category "Alliance war" to "Do not sync" if you do not need that data, and are only interested into "Vendor" category to get sold items data.
