I'm experiencing an issue with my Xbox one. It turns on but it fails to get past the troubleshooting screen with the error E102 00000C01 8007000. Does anyone know the reason this code exists? https://appuals.com/xbox-one-system-error-e102/
Your console had a system update that failed. You need to reset back to factory settings and load your console as if brand new, whole setup again. That should clear the error. This site should hopefully help https://windowsreport.com/fix-xbox-one-s-errors/
No. When you restart the game your save file will sync and all progress will be put back into the game
