Failed to load Colorreload-gtk-module

Hello, can anyone help me with this command, what does it mean and how to fix it? For context this error appears always after i try to install/search/list something through Terminal and once this Error shows up my browser (Floorp) shows me a box with the words "Floorp is already running, but is not responding" (even tho it works normally - i just have to close the box and like nothing would ever happened) Does anybody know what to do with it? My google search went nowhere so far. Thank you
