MM 21 crashing when trying to open MM 2019 map (with no warning or window)

Was a beta-tester for MM2021, and I don't recall seeing this back then.

On many of maps, which may share the basic template, MM 2021 crashes when I try to open them.  They open fine in MM 2019, and I can manually copy and paste the branches (via creating map parts in 2019, moving them to map parts in 2021, and dragging to a blank map).

I deleted branches to identify which topics might be creating a problem. Oddly enough I deleted everything and the map still crashes 2021. I don't see any way to attach a file here, but it's a 45KB file with a blank main topic. It crashes 2021 every time.

Anyone else see this problem?

Hi Jerry, 

I'm sorry to hear your MindManager 2019 map is crashing version 21. I will email you directly and ask for a copy of the map, which I will then pass to our QA Team for review. 

Best regards,

I am having the same issue when opening a MM 2020 map in MM 21.
