I'd recommend getting Microsoft Flight Sim 2020 with the Fenix A320 add on, Thrustmaster Airbus Sidestick and Thrust levers, and a rudder pedal set. Do a few circuits and landings, turning climb and descents.
Back in the day when I realised my scanning was going down the drain, flight sim helped me bring it back up to scratch. Every 6 months I'll normally fire up the sim to do a dry run prior to my base cx. It also helped keep me on the ball during the Covid furlough period.
