Compilation error: unable to find numeric literal operator 'operator""const'

Good evening
i had my lightsaber hanged on the wall working perfectly then i tried to turn it on and the saber said font not found. i formated the SD card reloaded all the sound fonts and it does play some sounds but not the inital “electric buzz” of proper functioning. while i was trying to compile the proffieino once again now it shows

Compilation error: unable to find numeric literal operator ‘operator""const’

i have no idea what changed :confused:
i would gladly accept any help or ideas.

The error message is not enough to figure out what is wrong here.
I need to see the full output of the compilation, your config file, and I also want to know the version of ProffieOS, arduino, arduino-proffieboard plugin, and the Proffieboard.

good evening. thanks for the reply
Continued resetting back to my original back up config file and suddenly it worked, u i do not know what it was specifically.

if it happens again ill try and document it here in more detail to aid future users.

thank you for the attention.
