I had a world that was corrupted on my Switch. I've spent hours trying to find out how to recover it, as it is significantly important to my son, but all of the processes that I have come across and tried have been ineffective or based on seemingly dated information.  I'm not sure why it is even possible for a world to get corrupted and wiped on a video game without a clear reason, but I would greatly appreciate some technical assistance in the recovery of this world. 

Thank you
