Well, I don't know, but it's better not to check it first, I wouldn't program it like that.
The original is already incorrect and so is the answer.
This won't start anymore.

The only explanation I can think of is that something goes wrong during the readout and this causes this error.

parseSection: GUID defined section can not be processed

Same result.
Don't reprogram.
Which programming do you use? CH341A
