Herelink QGroundControl error Upload Mission

[Alvin]

Can you try the solution mentioned here?

Mission transfer failed, Retry transfer. Error. Vehicle returned error: X/Param5 has invalid value (MAV_MISSION_INVALID_PARAM5_X) Param5: nan

Any idea why I cannot upload missions from QGC to the drone since firmware updates? Same error with Geofence etc. Also get an audio message about Mavlink? Thanks in advance.
