Hi Vossler,
first check please via the screenshot trick which folder "ESO thinks" your addons should be in:

-> How do I locate the live/AddOns folder?
Sometimes Windows all of sudden expects addons to be somewhere else...
After that check the folder shown at the screenshot, go 1 level up to /AddOns and see if the addon folders and files are all there and at the proper version.
MAybe manually download and extract the dependencies, and delete WHOLE folders of the addons and dependencies before extracting the new ones! Make all empty I mean so you can see what get's extracted afterwards.
During extraction make sure you do only keep the live/AddOns/<addonFolderHere>/ and files in it, and not something like live/AddOns/<zip filename>/<addonFolderHere>!!!
Do you use OneDrive? Disable it then or at least the sync of your c:\users\...\documents folders in OneDrive settings as this might block access to the users\...\Documents\Elder Scrolls Online files.
Same for Antivirus tools: Allow the live folder and the eso64.exe access (whitelist, add exclusion) for them so they can read and write all files properly.
If you get "user:/AddOns/LibDebugLogger/Initialization.lua:46: table index is nil" after login this may also break other dependent addons, like HarvestMap, yes!
Libraries are code reused in several addons and if the library fails to work the addons fail to work and throw errors too.
Logout, delete the file live/SavedVariables/LibDebugLogger.lua
Delete the folder: live/AddOns/LibDebugLogger
Reinstall the newest version of LibDebugLogger then and see if tis fixes all errors.
Or at leas the LibDebugLogger error is gone then?
If HarvestMap is sill broken but LDL was okay, logout:
Rename the file live/SavedVariables/HarvestMap.lua and check if this fresh files fixes the errors then.
