Anyone else unable to play Forbidden West with PSN down?

I'm playing the PS5 version of FW using my PS4 discs, and today, when I try to launch the game, it tells me to insert the disc, even with the play disc inserted.

The disc looks clean and when I put it in, the PS5 menu jumps to Forbidden West, so I know it can "see" the game.

Is the game to able to recognize my PS5 license with PSN down?
