i recently started using blender 2.8 (was previously using 2.79), and out of the sudden my default tab goes empty. i can't find my objects anywhere. however, if i go any other tab - animation, uv editing... - it's all there! i've already tried deleting the Blender Foundation folder, but had no luck. anyone knows what i did wrong and how i can fix this? thanks!
Sounds like the view has gotten lost in space somehow. You can try pressing Home to zoom the view to the currently visible objects (where "visible" means not hidden or in a hidden collection), or you could use A and Numpad . to select everything and then zoom the view on the selection.
