Can you just remove the screws, slide it up, then pull the bottom out intact, then remove the top? Looks like you got some wiggle room.

For DIY - this is also a placeholder.
That's definitely how I'd start tackling this issue. The bottom tab is just barely stuck. FWIW, I am a contractor.
Update: used a utility knife to cut enough board away to get one tab and the screws out, then slid it down and was able to wiggle it out. Now on to the other receptacle the idiot did the same thing to
They make plastic spacers just for this purpose. You can probably find them at your local big box hardware store.
Use the spacers!
Aw c'mon, Lutron isn't that bad. A lot of people actually like em.
Let me preface this by "I'm not a contractor". I'd use a multi tool to expand your cut a little bit on the top and bottom, then use "outlet spacers" to move the switch forward.
I think they make box extenders that might help this situation.
The funny thing is… I have them, and planned on installing them, just after the board went in. Just didn’t plan on sealing the outlet into the box.
Cut it out, install a box extender, then put on oversized plates to cover the mess
Get an oscillating multi tool, cut out the switch, then use spacers to bring it forward.
