Playing on Hard with 3 players total, we encountered what seemed to be an unsolvable puzzle.

We're meant to bring electricity into the room to power a electric coil in the top right of the room, however there's no way to bring the electricity close enough.

Solutions shown elsewhere / in walkthroughs show players using a plank through the doorway, except there's a collider in this version of the puzzle and a plank cannot be placed midway through it -- as such with only one available plank, and the coil in the top right of the ceiling, it's nowhere close.

Amadeus cannot summon 3 items at this point in time, the coil can be brought down but does not reach, we were 100% stuck for ages.

Eventually I loaded in solo, reloaded, friends joined and we solve the "single player" version which was trivial (and had an electric source by the doorway, instead of having to bring it over to the doorway in the first place with plank 1).

This is the room:
