Close the game normally instead of force-quitting it
Verify that antivirus or Windows Defender is not blocking file writes
Install the game in a non-protected folder like `C:Games` instead of `Program Files`
Confirm that the `reframeworkdata` folder exists
Delete any corrupted REFramework config files and let them regenerate
Update REFramework to the latest version
Ensure the game is not running from a temporary or virtualized location
