Experiencing the same thing now. Just booted up and last saves are dated 23 Nov; I actually closed it down at just gone midnight (after saving, ofc) on 3 Dec.
My trophies are all there, including the ones I earned last night (technically just minutes into 3 Dec) and my PS5 says I’ve 113 hours played.
But my 23 Nov ‘last’ save had it on 86 hours. Very odd. I’ve followed your advice and closed the whole thing down. It’s getting late so I’ll call it a day now and hope and pray when I try again after work tomorrow, my actual last saves will be there again.
EA needs to fix this. It’s not a PS5 thing it’s a Dragon Age thing.
