Hey, I had this same issue. It comes down to the game not continuing to jump to a cutscene while loading in between and gets stuck. What I did wasn't lowered graphics or any of the other suggestions cause they didn't work mixing and matching or anyway.

What I did to fix the issue was left my graphics at the maximum(what I use) and put the game into Fullscreen mode but lowered the Refresh Rate/Hz to "24hhz" and it loaded into the next cutscene. (I also priotized the AcValhalla process cause this seems to be drive reading issues).This seems to be an issue with the game itself with how it loads cutscenes from HDD/SSD speed processing cause I used this fix from a suggestion of a cutsecene people had issue with for the very first big boss fight in the standalone Valhalla game's story.

So anyone out there who runs into this issue and the other options don't work, lower your refresh rate to 24hz but need to be in fullscreen mode for that option to not be grayed out natively. And you can raise the AcValhalla process priority in task manager to High if that combo needs to be done.

To the Ubisosft support team looking into to this I don't know how this issue would be fixable for the entire game with a quick hotfix update or a full blown update that recognizes there are multi parted cutscenes that should be loaded in full before started the first cutscene. I would guess that would be a bigger update changing code for entire cutscene segments but it seems the issue is the cutscenes that are loaded in multiple segments have a small chance of freezing out and sticking the game in limbo mode of not being able to progress or play until issue runs its course.

As of update 1.5.2, this game-breaking bug is still not fixed.

However, as suggested by Thombro911, there is a workaround. You do not have to change your graphic settings or your monitor refresh rate. You need to cap your frame rate at 30 frames per second (console style). I personally use RivaTuner, but it might work with the ingame frame rate limiter. By limiting the frame rate to 30 fps, the cutscene properly ends and the boss fight can start.

After the boss fight, you can change your fps limiter back to your prefered value.

@ryusennin Thx. This simple hint was the solution for me as well. After limiting FPS to 30 the fight starts smoothly. Thx again.

Limiting the FPS to 30 before talking to Ivaldi did the trick for me

NOTE: Lmiting the FPS to 30 while the cutscene is stuck did not fix it. You need to load a game before the conversation with Ivaldi

I'm having the same problem and even if i try the workaround of making the gfx low and hit spacebar to skip it's not happening. Can we know when can this be fixed? or is there any way to skip the whole quest and move on?

I overcame the problem in this way - first I started another quest (Kara's Domain), then I saved near the Grenhellyr hideout. After that, I transferred the game to the SSD drive, updated it to 1.5.2, and ran my save. Walked into the shelter, launched the cut-scene and the bug disappeared, after that the battle with the boss began. If this helps someone, I'll be glad.

@ereke_kz-0 mine is already in the ssd and i tried running with low graphics too but it didn't work at all...there are no more quests left for me except this. i'm doing the valkyrie arena now but i returned back and tried and it is stuck... @ubisoft should release a fix. it's hampering the user experience!

I have the same problem and nothing has helped that has been mentioned here. Since the bug is apparently known for months, I wonder why there is no fix yet.

I have solution for anyone who tried all workarounds mentioned here and it still doesn't work. Simply use Nvidia Geforce Now app and lauch game there, beat the boss, watch cutscene, save game and close it. Then launch game on your device and you can continue playing after the boss fight. I hope it will help someone.

@ubi-borealis

I lowered the frame rate. I entered from another location on foot. I loaded the save manually.
Still getting stuck.
