Some Steam games have a buggy or broken cloud save feature and you end up being stuck in a failing sync loop. To fix this issue:
- Open Steam console by opening Run/hit Windows key + R and type
steam://open/console
- Inside the console window, type
testappcloudpaths {GAMEID}
- Go back to the game in your library, press the cloud logo, and it should sync.
{GAMEID} is where the game ID goes. For example, for Devil May Cry HD Collection, you would type testappcloudpaths 631510
. You have to do this every time you want to force the cloud to sync.
You can do the same thing on your Steam Deck using desktop mode.
