Arbiter of Divinity Questline Bug

Late last night, I was trying to complete the Arbiter of Divinity questline when I died and attempted to respawn. After respawning, I was stuck on a bugged screen.

I then tried relogging and returning to the boss, but I was unable to use the portals in my hideout. After that, I created a new instance and attempted to reach the boss again, but the boss is now no longer spawning.

As a result, I am currently stuck in the questline and cannot continue my progression.
