Failed to read the configuration file

What happened?

The printer displaying the message: Failed to read the configuration file. Try to reset the printer. If the problem persists, contact support.

Error name: Failed to read the configuration file

Error code: #10505

This should only happen in case of a bug or hardware failure. If the problem happens once it might have been some rare EMI (Electro-Magnetic Interference). If it persists either the system is corrupted or the A64 hardware is failing.

How to fix it?

Restart the printer, and flash the firmware. If still unresolved, replace the A64 controller board.
