If it isnt working, the fix is simple: Reiza brought an update for formula ultimate, so at the moment the skinpack will go into a formula_ultimate_2022 folder if you just copy them. Locate it and put the skinpack into the new formula_ultimate_2024 folder and rename the xml-document "formula_ultimate_2024".
The exact path from your steam folder is: automobilista 2/vehicles/textures/customliveries/overrides/formula_ultimate_2024
And the actually review: Looks really awesome, nothing more to say! :-)
