Hey pigsy_100,
Sorry to hear you've run into a corrupted save. One thing to check is whether you have a previous version of the save available through PlayStation Plus cloud storage that you can restore. If the cloud save has already synced with the corrupted version however, there unfortunately may not be a recoverable backup.
We do not have any method to push cloud saves to your console on this end, I'm afraid.
Does every other Career Mode save load normally, leaving only this one causing the crash? If there isn't an older PS Plus cloud save and every other Career save works, unfortunately this particular save is likely unrecoverable.
