After the Keeper's speech, my character drinks the potion, the screen effects play, my character falls to the ground, then my game freezes. This has happened every time I've tried so far, I've tried it in multiple viewmodes and I've toggled the Window setting. Any suggestions or help would be appreciated since I'm otherwise completely stuck as far as the main story goes.

Try lowering the HUD-opacity.

Alternatively, if that doesn't help, do you have anything activated in experimental multithreading? If so, deactivate and try again.
Activating One-Tweak might also help.

HUD-opacity didn't help, I don't have anything in multithreading, and I've already tried with and without One-Tweak. I've tried playing this scene like 20 times now and it's always the same thing.

It's something in the transition because my game stops on like the last frame so that I can still vaguely see my surroundings, and if I push the quest forward with console commands without listening to the speech and drinking the potion I can still go to the cell and I think play through it (Haven't fully yet so not sure if that breaks anything)

-UPDATE- Seems the transitions in general are bugged for this quest. I played through it till it tried to send me back and then it just froze again.

Then... I don't know sorry. Maybe it's time to put it in the bugtracker? With uploaded save and everything.

I also apparently can't play any stage at all of mq06 because for some reason they're all teleport triggers which freezes my game. So for the time being I've skipped over it and hopefully it wasn't super critical.

So I can get all the way up to where Jorek (?) asks me to drink the Strange Potion after saying the rites and afterwards I collapse on the ground and vision starts to fade. Like... just before it's done fading to black it freezes. I've been trying to hold out for a working patch but this bug is ever-pervasive.

Any fixes?

Have you tried changing your settings?

My game froze during other parts, lowering HUD Opacity worked to get it going for me again.

What also could help is deactivating experimental Multithreading or activating OneTweak in launcher settings.

Hmm... I lowered my HUD opacity to the lowest and activated OneTweak. I didn't have experimental multitracking on in the first place so I couldn't deactivate that. Same freeze.

Maybe setting all options to low, reflection of all things off etc.?

I don't know what else to tell you except, if nothing else works, to report it in the bugtracker. Sorry
