Pump'n hoses problem installation on Xbox series X

[WolFoX28]

Hi,

My friend bought the mod on xbox series x , he downloaded it, but on the game interface he is told that the mod is not installed. He can't play with it.

He deleted it, re-installed it, cleared console cache, re-downloaded the game, factory reset his xbox but still the same problem.

Does anyone know a solution to this problem?
