Viewport not rendering

[Meg14 0]

My viewport isn’t rendering on any final quality renders? 

When I render the actual drawing it works but not the viewport. 

Does anyone have any suggestions as to why this might be? 

Thank you

Does it render as wireframe or as a black/white rectangle? Does the same thing happen in other files or just this one? Same issue after restarting?

It does the same after restarting, and the rectagle doesn’t show, the screen just goes dark

Is your default image compression JPEG? Does it work when you switch to PNG? Does it work with other RW modes?
