Data recovery on MBP 15’s SSD corrupted drive?
Is your drive formatted as an HFS+ (macOS Extended) or APFS volume? If it’s HFS+, you can try DiskWarrior. (Though, from the sound of it, the corruption may not be in the volume itself but rather in the partition map, and I don’t know if DiskWarrior is able to fix those errors. May be worth reaching out to their support team.)
