Can't start Apache again after removing Litespeed

Hello, I have Litespeed installed on my VPS, I tried to uninstall it and back again to Apache, but I am getting this error when I try to start or restart the apache! Restarting httpd (via systemctl): Job for lshttpd.service failed because the control process exited with error code. See "systemctl status lshttpd.ser
I had to install the Litespeed again to be able to start the httpd service again. Any solution? Thank you
