Nothing is visible on canvas

I have just installed Lunacy on windows 10 machine.
My OS is Windows 10 Home edition 10.0.18363 Build 18363
After installing when i open tutorial sketch file i do not see anything on the canvas.
If i try to create objects on canvas i can see XMl or CSS code but do not see any graphics on canvas.

Please, try to update the video drivers and run Lunacy once again after disabling your antivirus.
