Help with Missing Filename Error?

hello everyone! having issue code have had no issues running before. today while trying upload code (no changes made) received error:

avr-g++: error: missing filename after '-o'

exit status 1
error compiling.

this first time have received error. mean? using fastled library adafruit pro trinket.

here code using.
