Simply go to PLAYMODES then NEW CAREER, use any squads (I used download latest). Then from create new manager, go up to PLAY AS REAL MANAGER. I went to Australia and chose PATRICK KISNORBO from Melbourne City. Advance until you are in the HUB, go to OFFICE, then CALENDAR, go to the 30th of JUNE 2023 (make sure it is 2023 and not 2022) and advance till that date. You shouldn't be fired but on the odd case you are just try again (any A-League team should work), when the simulation has finished simply click END SEASON then ADVANCE.
I created this video to help:
Hope this helps.
