Main Quest blocked - 1st Boss bug

Hi everyone,

After seeing the first boss cutscene, the boss npc was stuck and later it desappeared. I couldn’t attack it.
Later I left the area, closed the game, restarted it and nothing was in the area. I tried dieing and also nothing changed.

Can’t progress in the game due to this.

I found a work around. When selecting the realm to play in, there the option to load a Backup. From there I had to load an old file (lost some progress) and the next time I came to the boss, it did work as it should have.
