macOS Catalina Blue Screen after update during inactivity

I updated to macOS Catalina 2 days ago and since then getting a sudden blue screen / color distorted screen when the iMac is inactive. Instead of going into sleep / screensaver mode its like the entire screen have a distorted color splash screen.

I have Irvue app running which changes the desktop wallpaper. Not sure if with Catalina OS upgrade the app has become in compatible and is contributing to the issue.

Model: iMac (Retina 5K, 27-inch, Late 2015)

Graphics: AMD Radeon R9 M390 2 GB

iMac Line (2012 and Later)

Please uninstall the wall paper app then restart in Safe Mode and then restart normally and test.

Martina,

Thanks for your help with those that have an external monitor.

My computer does not use an adapter as it is an iMac.
