ok so this was a thing on f1 2021 at launch too there was a work around so maybe try this
Host of the two-player career should go to: Multiplayer > Social Play > Create Custom Game > Choose 'No (Open)' Lobby > Settings > Lobby Options Change car category > F1 2021, then change car performance: realistic Exit to main menu Host loads back to their 2P caree
replace 2021 car with 2023 car
This works! Only difference is that the “equal performance” option is in “simulation settings” now. I just did this and it fixed it in 2P career.
