When I started MATLAB and saw the messages below.
I have tried to uninstall and re-install MATLAB, but those warnings are still here. I'm using a MacBook Pro. I also have a R2020b MATLAB installed in my laptop because I need both versions of MATLAB. I'm not if that's causing the problem.

"I'm not if that's causing the problem."
The problem is that you have added many subfolders to the MATLAB search path, that should not be there.
To fix those warnings, remove all FieldTrip folders from the MATLAB search path, e.g. by calling
restoredefaultpath
Note that the FieldTrip documentation explicitly states "In general you should not add FieldTrip with all subdirectories to your path... there are some functions for backward compatibility in fieldtrip/compat, which should only be added to your path in case you use the corresponding old MATLAB release" and then it procedes to explain exactly which toolbox folder needs to be added to the MATLAB search path. Note: folder, singular, i..e only one folder.
source: https://www.fieldtriptoolbox.org/faq/should_i_add_fieldtrip_with_all_subdirectories_to_my_matlab_path/
The FieldTrip documentation also explains how to reset the MATLAB search path and start again.
