Cant edit mesh

I’m modeling an object and i decided to separate it in 3 parts, the parts that are separate from original mesh are good to work with, but the original one when i select it in object mode to try and go to edit mode it disappears i don’t know why, if i want to select his faces nothing shows same in verts etc, ( the object is not hided )

i really appreciate any help .

You will get better help if you share the .blend file here.

Accidently hidden somethng ?? Try unhide alt-H.

yes, apparently i hide it twice or something like that, thx everyone solved.
