ISSUE: Error:No Checksum with line number. Last Line: 0

1. Open SD Files on LCD
2. Upload File to SD from OctoPrint
3. While file is uploading go back from SD Files on LCD
4. LCD goes red with white writing "Error:No Checksum with line number. Last Line: 0"

This is only solved by power cycling the printer.

Will need to investigate what the actual cause of this error is. Probably related to needing to remount the sdcard during some flow. This error is could just be shown instead of locking the user on the the error screen.
