I lost my shared save

[DropbearDrops]

I lost my shared save because my kid accidentally joined the game I was already playing on PC from my account on xbox while I was using the account on PC. It kicked me from the game and I haven't been able to load it since because it says I have lost the original save. He can still load it from his account on the xbox (we have a shared save) but because I own the shared game, I can't edit the save file or shared files from his account. Is there any way to recover the active save file?
