I forgot to mention the flashing and reset of selections happens in the project list menu as well, its also difficult to change any rendering settings in the main editor in project settings. I'll click on project then the drop down menu and it disappears when the program flashes. so a few tries and I can get into the settings if I'm lucky -_- I did try the rendering options: compatibility and forward+ neither worked.
You could try making a copy of your project, and importing it into 4.4RC1, but that would probably just bring its own set of issues. It is worth a try to see if that may have been a bug fixed later on, otherwise I think you may have to use Godot on your laptop since I don't really know what the root cause of that issue is; it seems entirely a godot issue as far as I can tell
