Save file is there but won’t restore to game (no error)

One specific save will not restore to sims game.
Yesterday my game froze and my last save was an
hour and a half prior. Id done a lot in that hour, so I
went and bought ps plus to retrieve the game
data I lost when it froze. (I'm on ps5) there were 4
saves, the one I wanted, 2 from earlier in the day
and 2 from April. I tried restoring the most recent
one and it wouldn't restore, it kept restoring the
ones from earlier in the day. I deleted the two
saves from earlier in the day, and stupidly didn't
save them in the cloud so now I lost all my
progress and it shot me back to April 19th and I've
done so much damn work since then. I didn’t delete the newest file that I wanted, it’s still there, it just won’t restore.

 I'm now wishing I had just gone back to the save from an hour because losing an hour is better than over a week of progress)
I bought ps plus, and the save file I want is literally
in there and will not restore to the game ( the
other two save files restore fine but they are from
April! I don't know why this one won't restore and
I'm sick thinking of everything I lost. Especially
When the save file is actually available, it just
won't work. When I delete the saves from April
from console storage and just leave the most
recent one, I open the game and the only option is
to start new. So clearly this newest file is corrupt
or something. Please tell me there's a way to fix
this
