All components, bodies and sketches disappeared

[tomerinbar1]

I'm working on a project, and suddenly everything disappeared.

I check that every component, body and sketch is shown, try to restart Fusion 360, Restart PC, go back in timeline, nothing help, couldn't find a solution.

I export the invisible component to 3D Printer and it shows up normally in the slicer.

I hope that the uploaded file is useable, please let me know

everything is still there.  You have just created a HUGE construction line, so Zoom All is zoomed out so far that all the components are a single pixel.  Zoom in and you will see them:

Zoom out and you can see this construction line:
