[Cura 4.71 - cannot see what I am printing]

In Cura 4.71 I cannot see the object that I am printing

here is what I see:

https://ibb.co/JmyzNLF

 

The print job is actually printing but in "monitor" view I cannot see the object.

I "preview" view I can see the object.

 

I have tried uninstalling and reinstalling the software but the issue persists.

My printer is Ender 3 Pro.

 

Also, every single object that i tried to print shows "Print setup disabled. G-code cannot be modified."

I do not know if that is normal.

 

thanks for any pointers that you throw in my direction.
