Hello, this kind of counter-lane-change-deadlock is known to occur in very short weaving sections and the solution is outline here: https://sumo.dlr.de/docs/Simulation/Motorways.html#combined_on-off-ramps In your situation there might be something else going on because the road ahead of the off-ramp should be long enough to permit both streams to exchange their lanes via regular lane changing.
