these 2 things keep happening when i try to play 1.17.1??? anyone know how to help? @MojangSupport

none of the stuff i have googled works, and i am using the official minecraftlauncher. i noticed that this has all happened after i inserted -Dlog4j2.formatMsgNoLookups=true in my jmv argument. i did that though because of the security flaw with java recently. do i reset it??????
