Can't play REDSEC on PS5. Error says "Install REDSEC”, but already installed

I don’t own BF6, but I’m trying to play REDSEC on the PS5. But anytime I try to go into the game mode I keep getting an error saying that I need to install REDSEC and after clicking on manage files it tells me that I need to purchase the game to play. 

On my PS5, I have installed the BF6 client, REDSEC, HD Content pack, and REDSEC HD Textures pack. I tried uninstalling and reinstalling the entire game on the PS5, deleting and reinstalling only the REDSEC portion of the files, but neither made a difference and it still won't launch. Anyone else run into this issue or can help me play this game?
