Cant find A11y bus? Unknown Terminal command for me.

Hello I might not be the greatest Linux Terminal user, but I do not recall installing something that would make this error appear. 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
