Can't play RDR2's story mode on main account.

Is the console set to "Home" for the account that purchased RD2?

Try to remove your profile, then turn off the console and remove the power cord; wait for 1 to 2 minutes before plugging it back in and turn on the console and sign in!

If the issue persists, I would strongly suggest trying the troubleshooting steps below:

Settings > Network Settings > Advanced Settings > Alternate Mac Address > Clear

Then select System > Settings > devices and streaming > blue ray > persistent storage > clear three times > restart console.

Also, It would be great if you can delete the local save of the game.

If the issue persists, try to soft reset your console!

Didn't work.

I guess I won't be able to play it until the Online mode is removed from Game Pass so the game doesn't think I'm trying to play it from there instead of from the other profile.

Just to confirm, do you have the full game installed? There is the Full game which is what you said that you purchased a while back. There is the Online mode which is available through Game Pass or purchase. And there is the seperate Story mode add-on for the Online version. So you would need either the full game installed or the Story mode purchased as the add-on for the Online mode.

Which way do you have it set up?

I have the full game installed.

If I try to play using only the profile I bought the game with, it lets me play the story, but if I try to play with another profile even though the account that owns the game is also active, it only lets me play online and ask me to buy the story.
