Hi,

thank you for the reply.

Please try (running the sketch/restoring the firmware) again so the error occurs again, then go back to the home page in CircuitBlocks, scroll to the bottom, and in the footer you will find a “Send error report” button.
Clicking it will open a window showing all the information which will be sent, which includes the error that happened as well as some other info about your system that might help us resolve your problem.
When you click “Send report”, the report will be sent to tour servers, and you will get a report ID. Please get back to us with that ID and we’ll be able to assist further.
I have the same situation. My Nibble works fine, but after uploading a custom program I cannot restore the firmware. I get the same error message as @gcaprio. I use MacOS 13.1 and CircuitBlocks 1.9.2
fyi, I finally tried again and uninstalled everything and reinstalled both Arduino & CB. I also manually installed the Arduino boards and I was finally able to restore the firmware successfully!
I have the same issue but im on windows I uploaded the game from circuit blocks and I am unable to revert to my normal nibble it just came up with this
