You’ve repeated this phrase a lot in your responses, but simply put this is not how software/the game/add-ons work together. When you have an add-on update waiting to be installed it doesn’t automatically prevent you from loading zones in the game.
All we can do in this forum is troubleshoot. If you’re interested in doing that, myself and others can help. But if you’re just here to shout into the void, I’ll let you continue on that path solo.
The steps you need to do for troubleshooting and what reports to provide are pinned at the top of this forum:

If you’d like help, add these in a reply.
