Demon form crashing game during sekhemas trial

Hello,

I have been trying to finish the trial of sekhemas (4 stages) and was finally on a very good run after changing build.

Unfortunately, I had several crashes of the game, it says something about the demon form (see images).

It is very annoying as I was finally very close to finishing, and might not be able to at all because of this bug...

(including the images directly doesn't work apparently, so I can only give you the link).

Hope it helps, and hope you can help me !
Thank you
