Steam to Gamepass file remains .SAV

[brokeyabutt]

When trying to convert the file from a Steam save to a Gamepass save, the file remains a .SAV file, which the Gamepass version of the game just ends up deleting from the save location as soon as the game boots up. Any extra steps I'm missing to have a Steam to Gamepass conversion?

so from steam to GP file,
try rename that "decypt_out.sav" with one of your GP version, like this "675383F30FA04AE4A40CF9A46665BD85" it must has no file extension.

then replace it and load your game.
at least it works for me
