Where I'm from, every junction box needs to be accessible (usually a little dry wall access panel); but we all know some naughty people who bury them behind walls. Depending on where you side....

I'd pop the box circles out on the side where you need the wired to go, put little plastic safety pulls in the holes, run the wire through and into a new electrical box in the location you want. If your wire isn't long enough, I'd wire nut long pig tails in your current box and out the side holes into your new box. Then I'd bury your old box in the wall. I'm bad.

Remove any fasteners holding the box and see if there's enough play in the conduit to move it over a few inches. It'll depend on where that conduit is attached to the stud.

If it moves far enough then just shim the stud with 2 more 2x4 scraps and reattach the box (cut a new hole in the drywall for it).

If you can't move it far enough then you'll have to open that back wall further and figure out how to get some play in the conduit.

Weird that there's metal conduit in the wall. That's bad luck on your part.

TLDR: IMO, don't take the "quick and easy" way out. In retrospect, I should have bit the bullet and had the entire slab demoed out and poured new with rebar. I could have inspected the entire plumbing & water systems/foundation wall footings, and it would have been done in a month at roughly the same price.

Jacking the slab didn't work for a number of reasons:

  1. My house has three support/jack posts cast into the slab supporting the main floor beam. The way the support posts were incorporated into the structure, they had been set into a unified concrete footing (lazy pouring approach of the early 80's). This created a problem when attempting to lift the slab, as isolating the post footings from the slab without compromising the footing or jacking out sections of the slab wasn't possible.

  2. Line locating. The sewer and water line locating completed by three different plumbers was not accurate. I was told accuracy within 6", and it was out in some spots by almost 18" by two of the three plumbers. One drill went through a line when the slab jackers were installing their ports, and they ended up pumping enough 4lb foam into the line that flushing toilets or running taps into sinks was no longer an option.

  3. Oversold/Underdelivered. The structural engineer and unaffiliated slab lifting company I used were both specialized in residential/commercial foundation repair. Engineer convinced me that it would be cheaper/easier/faster to do poly jacking than demoing the entire slab and repouring. The slab lifting company swore up and down that it could be done and I'd have level within 3/4" over 20', which I was good with. When all was said and done (three separate lift appointments), I was still 3-1/2" out at the lowest point and $17k poorer, in addition to a bunch of sewer line that I had to replace at about $1200 in material for concrete and pipe/fittings due to standard waivers that were part of the job contract. Once I jacked out the slab around where the sewer lines were, I saw some issues with poly lifting. The slopes of my pipes had been messed up by the sagging slab, and then messed up differently by being lifted. There was a lot of sheer stress on the system as I cut it apart.

Ultimately, it was a good thing that they messed up the sewer lines, because jacking it out was the only way that I would have discovered the culprit leak.
