"I lost everything"

My switch suddenly died and had most of my shiny/event Pokémon on it going all the way back to GBA (Pokémon Shield). Is there anything I can do to recover them or is everything gone forever? I know Pokémon saved aren't able to be backed up to the cloud and Nintendo wipes consoles sent in for repair. I had a complete paldea living dex waiting for home compatibility and and in progress competitive team too... via /r/pokemon https://ift.tt/M2ULsK6
