game file save

I have been playing on my ps4 for a while now but I just got a Nintendo switch and was wondering if there was any way for me to move a game file save across to my Nintendo so that I don't have to start a whole new save but I don't have the internet subscription on either the ps4 or the Nintendo...

I was playing and lost power to my laptop while doing so. When I restarted my computer and went to play my game file has disappeared from the load out screen. Is there anyway to recover it? I was so far in that game file. ;n;
