PS5 Black Screen when trying to continue in campaign.

BF6 installed OK on my PS5, and I started the campaign. Second day, it wouldn't load until I had re-booted the PS5, then played normally. Today tried to continue the campaign, splash screen shows then black screen and nothing. Re-booted the PS5 again, still won't load, black screen again.

All patches up to date, no other issues but game is unplayable. NOW WHAT???
