Ok so the Unity bug seems to be already existing here (https://valheimbugs.featureupvote.com/suggestions/158529/unitydll-crash-problem#comment241398), I did upvote it, bringing a bit more of informations.

However the orignal bug of this steam post does not seems to exist. I'll create it.

Edit:
Here's the report on the tracker : https://valheimbugs.featureupvote.com/suggestions/159524/image-freezing-while-game-still-running.

Feel free to upvote it if you encounter the same issue.
