The problem here appears to be that your Matlab ROS support uses a different version of the control_msgs/FollowJointTrajectoryActionResult message than your ROS Melodic install.
The error message about the MD5 sums no matching is telling you this.
As to why this is the case I wouldn't know. control_msgs/FollowJointTrajectoryAction hasn't changed in many years, so it's unclear to me how this could happen (as a guess: perhaps Matlab is using rosjava, in which case this might be caused by rosjava/rosjava_bootstrap#16, but again: just a guess).
As to how to fix this (or work-around it): I would suggest you ask Mathworks for support. Assuming you haven't made any changes to ros-melodic-control-msgs on your Ubuntu machine, the problem would seem to be on the side of Matlab.
