is it burned?

I've been having problems for a few days to put the green led on my switch. I have disassembled it and I have seen this microcontroller like this. Is it burnt? it doesn't look like glue.

Do you know any way to fix it?

it looks like it was laser etched to remove any identifying information from the chip

they used a chemical to erase the chip markings. usually to prevent cloners.
