Hotfix v5.04 - Repair Game Startup

Thanks to Cannondalex, skala641, and kelek22 for sending logs that helped track down a startup crash.

Some players were getting a black screen or failing to load the main menu when starting the game. This was caused by a rare save file issue that the game mishandled during startup. In v5.04 that should be fixed so the game recovers from these cases and runs normally again.

Your progress and high scores stay safe. If you experienced this bug and will be restored from Steam when you launch.
