my microphone has long delays after downloading the app

i wanted to test out voice ai, but i didnt know how so i tried to uninstall it and i didnt know how. so i just ignored it. after a few days i played with my friends on discord and they had a HUGE delay on my voice. they didnt hear me for about 3 minutes and usually i didnt get their attention soon enough. i tried uninstalling but nothing worked and i didnt find any buttons to delete the app. please help i want to delete the app and fix my mic delays (its a built in laptop microphone to be exact)
