Most Launcher issues resolved here
Although Zenimax/Bethesda prefer you to launch the game via their launcher, it does pose some issues from time to time with regards to logging into the game.
You can try to log into the game directly via the game file instead which worked for me until the launcher issue is sorted and am posting this as a temporary fix - find the game's eso.exe file (usually found below)
C:\Program Files (x86)\Zenimax Online\The Elder Scrolls Online\game\client
and click the eso.exe
see if you can log in without any errors or issues. You can also right-click the file and pin it to your taskbar for a one click method if it solves your login problems.
