@soonerbrink, can you excavate on the outside of the flange next to the washer to see if there is PVC there or if it is open? You may still need to get two wrenches and have one grip the bolt above the nut and another to grip below and see if you can remove the nut to see if that gives the bolt any movement.
Unfortunately, I don't see a way to deal with this with the toilet still in place. You will need to have the toilet removed to mess with the flange/bolts.
I hope you can get this resolved. Worst case you could get an inside cutting attachment for PVC and remove the entire flange & replace it with a new one so it is slotted correctly.
