This is the second monitor screen that's causing MAVs. I think the issue may be trying to read screens that have no content on them.

And how can you explain that it is not crashing for me?

Not sure. I noticed that I was able to use all of the monitor screens just fine with the custom map I made with the editor. However, I am using Windows 10 on an x64 based OS. I've got nothing. Thanks for all the replies and support.
