Same error as a lot of users here, but I'm running Catalina, so I'm not sure if that changes things and I would rather make sure I'm going about it the right way so I don't make things worse.
I tried to delete a partition, and disk utility crashed halfway through. I restarted and got the folder with the ? on it.
I would greatly appreciate if someone could guide me to fixing this without losing all of my data. Thanks.
E: I realise I should probably add a little more info. I have an Early 2013 15” MBP with the 500GB SSD.
