Crashes when started on second monitor

I am using the latest version of Toon Boom Harmony 20 on a fairly new Windows 10 machine. I am having trouble opening the program on my second (pentablet) monitor (XP-Pen Artist 15.6 pro). The program will open a project and it will say “Not Responding” on the tab. There are no issues when opening on my primary monitor. I have updated all my drivers and graphics card and reinstalled Toon Boom multiple times.

I saw a post with a similar issue dated 2 years ago but the solution was never posted. The post is in the link below.

This is quite odd for me because I never had any issues with my old laptop connected to the same pen tablet. I also didn’t have any issues when using it before on my current desktop. I took a break from animating for a bit and came back with these problems. I really want to get this issue fixed as I don’t want to give up using two monitors.

Thanks for your time and help!

Hey I have the same issue! You ever find a solution?

From what I’ve seen make you pen display the main monitor.
Also report the issue to support.
