Trial of Chaos Couch-Coop platform Bug

The platforms that drop you in/out of the arena move as soon as one character steps on. The second character would be stuck. The second character is only teleported in in the first trial (1/10).

Little to no room for error when stepping onto the platforms; even when I do it with both of my hands, one would still be left out.

As of now, I have been unable to complete the trial, and the most challenging part is stepping onto the platforms. xd. Please fix. Can't run Bloodmage without 3rd/4th point.
