Nibble malfunctions after adding custom game

To Whom This My Concern,

 We completed constructing the nibble and had it fully operational. My son attempted to upload a game to the nibble. After doing so, all of the issues started. Screen turning white, now is is completely black, and won't boot up. We tried to do the restore firmware button in the circuit blocks app on our Mac OS 10.15.7.  

The following is the error message received after attempting to restore the firmware:

Uncaught Exception:
TypeError [ERR_INVALID_ARG_TYPE]: The “path” argument must be of type string. Received type object
at validateString (internal/validators.js:112:11)
at Object.join (path.js:1040:7)

at WebContents. (electron/js2c/browser_init.js:3883:15)
at WebContents.emit (events.js:203:13)

I have uploaded photos of the soldering in case this helps diagnose the issue.

Any help would be greatly appreciated. Thank you in advance.

Hey @george.custodio,

Thank you for reaching out.

Please try restoring the firmware again once the error occurs, then click the send error report button and send me the number you receive.

Thank you,

Also, you can try resoldering some of the soldering joints.
