I've had troubles with the Formula 1 app for some time, but managed to get it running by installing it from Aurora, as the Play Store kept saying, the app is not compatible with my phone.
However, now it does not work at all, as it keeps stopping (here is the error message):

Did you manage to get it working on your GrapheneOS phones? I did enable "Exploit protection compatibility mode", but that does not make a difference.
