Send the save over from your Switch using FTP.
Very important, I want the save that you restored to your Switch that is causing issues, that is on your Switch. I don't want a fresh download.
Also, I want a screenshot of the files in the folder that you're going to restore.
As much as that is a sure fire way, repeated usage of taking out and placing back the SD card can kill the SD card adapter on the Switch (which is replaceable) and that part of the motherboard connecting to the adapter (not replaceable).
I won't recommend it. I know it happens, cause it happened to me.
