Storyboard Pro 7 crashes when two monitors are in use

My specs:

Win 10
Nvidia RTX2080 (latest drivers)
Monitor1: a basic monitor
Monitor2: a 21UX Wacom Cintiq (latest drivers)

The program crashes anytime I flip between timeline and drawing modes. If I unplug my regular monitor, and just have the cintiq, it’s able to not crash.

Another funny thing, with both monitors in operation, when I open and old project it says “this project is in use”.

So, I’m able to work but I can only have one monitor at the moment.
