for the reference I used adafruit_feather_esp32s3

#

it uses the tinyusb bootloader, but I currently use the CP2102, so I would have to remove the tinyusb otg parts

token "{" is not valid in preprocessor expressions is the clue there. An extra character or missing newline?

Probably not, which means the game becomes figuring out what's triggering that.

{' is not valid in preprocessor expressions" typically occurs when there is an unexpected brace in a preprocessor directive such as #if, #ifdef, etc

#

I think it has to do with the USB macros
