Right-click the file, select , check the box for Read-only , and click Apply .

By utilizing standard message wrappers, Ren'Py will automatically inject the UNKNOWN_TOKEN text directly into the frame without crashing the game engine. The Official Solution: Using Ren'Py Sync
Searching for a direct link between two devices suggests a server-based sync feature (like Steam Cloud). Steam Cloud sync works on a per-game basis if the developer configured it, but it often fails with this error because the token remains device-specific. renpy this save was created on a different device link
Ensure the game folder is named identically on both devices.
If the Ren’Py game is on Steam, the "different device" warning is rarer because Steam handles the synchronization of the persistent data for you. Ensure is enabled in the game properties on both devices. 3. Syncing via Cloud (Dropbox/Google Drive)
On your second device (the one showing the "different device" error): Right-click the file, select , check the box
: Maliciously constructed save files can execute arbitrary Python code, potentially harming your computer.
If playing via Steam, the cloud might have synced a save from a different OS (e.g., Mac to Windows), which occasionally causes pathing errors within the save metadata [3]. How to fix it Force Load: Most of the time, you can simply click
The error message is usually displayed as: Steam Cloud sync works on a per-game basis
If a game freezes on a black screen because of missing UI elements, you can force Ren'Py to ignore token validation by stripping the signing string.
To understand the fix, you need to understand the cause. Ren'Py saves your progress using a Python process called (serialization). This converts the game's current state—variables, image paths, dialogue history, and Python objects—into a data stream stored in a .save file.
