Failed to start sessions

Recently I install "Jonaburg-picom fork, It caused some issues , so I decided to uninstall that fork but couldn’t uninstall with ‘sudo pacman -R’ command . So again decided to remove default picom and i thought fresh install may resolve this problem. When I type “sudo pacman -R picom” , i saw two line of message like " dependencies required by the “manjaro-i3-settings” and it was also not removed… finally I forcely removed those two things typing " sudo pacman -R manjaro-i3-settings picom " and rebooted and now I unable to login . When I type my password it showing "failed to start sessions " .
Someone help me…
