MINI 3 PRO with RC PRO connects then disconnects

Ive uploaded my mission to Litchi Pilot on the RC PRO, I can connect the drone, but it connects then disconnects , connects then disconnects so it will not allow me to start my mission because of this connection issue.
Please Help

You have to FORCE STOP ALL other drone apps before running Litchi Pilot, including the classic Litchi app.
