There were 3 engine jet airliners with 2 wing engines and 1 rear engine like this, but never an airliner with 2 rear engines and 2 wing engines. 3 engine jets with 1 engine in the tail have all stopped being produced because of safety concerns over an engine in the tail where control surfaces are, but airliners with 2 rear engines are still produced since neither engine is actually in the tail. So why did nobody ever make a plane with 2 rear and 2 wing engines

You don't want the rear engines to ingest the exhaust from the wing engines. Also debris from wing engines risk destroying the rear engines.

This, hard to reach, hard to fix, harder to pay for.

Also, jets that are large enough to necessitate four engines usually have a large enough wingspan to accommodate all four.

This ^ Trijets pretty much only existed because of concerns that early Twin-jets wouldn't be reliable enough for long distance flights. With the increased power and reliability of modern engines there's no need for the extra cost and maintenance issues of a third engine.
