Can't complete 4th trial boss for 7th and 8th ascendancy point due to bug/crash

I get an 'Error Loading Type Metadata/Effects/Spells" error that kicks me out of the game every time he gets to 25-30% hp.

I had two trials that wouldn't let me zone into the 4th floor due to some terrain texture out of sync with the server bug. Had to restart twice, now I can't kill the final boss because I get booted every time.

Worse than that, the game preserves any honor loss from the previous attempt. First attempt I had 90% honor, 2nd attempt I started with 75%, now after a 3rd crash I'll start with 50% honor now.

Pretty annoying considering the last 2 ascendancy slots are massive for my build.

Pics of the bugs... Please help I literally can't do my ascendancy this is nonsense.

Did a full game reinstall and still bugged.
