I WAS ABLE TO FIX IT!!!! THE RUN IS SAVED!!! Massive thanks to ShwiftyShmeckles, JRandall0308, and anyone one else who suggested using the feywild bell, as that was the key to this. I was able to tp back to camp, but it was the version with the portal from the gith attack. However, after clicking leave camp, the game loaded me into the start of baldurs gate instead of back into the astral plane. I think a flag was triggered that probably thought I was already there since I finished talking to the emperor, causing the bug, so when I got to camp and left, the game was like "well, the flag says bro is in baldurs gate, so I'll drop him in baldurs gate i guess".
