Hello @Zlirg49,
this issue is usually related to a few new internal settings we've introduced in the Craglorn-patch. As you have already tried the Repair-Option, we suggest to you the following to resolve this issue:
Navigate to
NA-Megaserver: C:\Users\Username\My Documents\Elder Scrolls Online\live
EU-Megaserver: C:\Users\Username\My Documents\Elder Scrolls Online\liveEU
Locate the file UserSettings.txt and open it with Notepad
Locate the following two lines:
SET RequestedNumJobThreads "-1"
SET RequestedNumWorkerThreads "-1"
Change these values to:
SET RequestedNumJobThreads "0"
SET RequestedNumWorkerThreads "0"
If these lines don't exist in the UserSettings file, simply create them instead
Save the file, and quit Notepad
Restart the launcher and hit Play
Let us know, if the issue is still persisting afterwards.
