Can't see armature

I tried to show all layers, to check hide, Display/OnlyRender, eye flags. Really don’t know what I pressed, also I could not pick armature and switch between modes by TAB key.

Very confusing. You’ve done all the obvious things… maybe if you posted a screenshot and perhaps a Blender file someone will be able to figure out what’s wrong.

Welcome aboard - I hope this doesn’t put you off the software before you get started.

Try this (not sure if this will solve your issue, but worth a shot): Go to the collection that contains the “widgets” and select all. Tab into edit mode, then tab back out. You should now see the armature.

I appreciate all your replies, unfortunately we would never find out what it was, because I has randomly typed keyboard, and suddenly the armature get back(TAB key issue also has solved).

By the way, thanks ;D
