Pcan you try running the game using wine-crossover instead of gptk?
PSBrilliant! Looks like that's working. thx!
PPS
try with wine-crossover instead
you are using gptk, use wine-crossover
- wine manager in heroic's sidebar
- wine-crossover tab
- install the latest (or 23.something)
- set wine-crossover as the wine/crossover version in the game's settings
- delete this folder using finder `/Users/(whatever yours is)/Games/Heroic/Prefixes/default/Rocket League`
- turn on auto installation of dxvk
- try again
