That Commonevents has to be one of the weirdest I've ever seen.
I don't think that was made with the official MZ editor.
I've changed the core MZ plugin parsing for Commonevents to make it no longer crash, which I'm definitely not going to regret, and I'm not even sure if it exports correctly now, because I'm not sure what those bits are even supposed to do.
Please try again with v2.040.
