Crash with "SystemInvalidOperationException: DialogHost is already open." #242

Version

ver 2.4.4 / Windows 10

Details

I've experienced this error several times in a row when playing around with display resolution and DPI scaling. I've got a dual monitor setup, and it appears to happen when changing those settings on the second display, although I can't be 100% sure, because the issue isn't exactly reproducible at will. It just seems to occur randomly after changing the resolution/DPI-related Windows settings.

This is what I see when the program crashes:

Then, after pressing "OK":

Next, Lightbulb crashes and needs to be restarted manually.

Steps to reproduce

Play around with monitor resolutions and DPI scaling with LightBulb running in the background. A multi-monitor setup may or may not be required. I apologise for a lack of more specific steps, which is due to being unable to reproduce the problem at will.

Can you please try the latest CI build to see if it fixed the problem?

Difficult to say for sure, but I've tried to change the DPI and resolution several times in a row, and the program didn't crash during the operation, so let's say that it's fixed 🙂.
