I installed the computer vision toolbox and tried to instantiate a detector object for maskrcnn:
detector = maskrcnn("resnet50-coco")
This gives an error:
Error using maskrcnn
The specified superclass 'deep.internal.sdk.LearnableParameterContainer' contains a parse error, cannot be found on MATLAB's search path,
or is shadowed by another file with the same name.
The error persists after running restoredefaultpath.
I'm using MATLAB R2022a.

I understand you are facing an error while trying to create a "maskrcnn" object.
Generally, the error message encountered by you is received when there is a user-defined function in the MATLAB search path which has the same name as the MATLAB built-in function. In order to resolve the issue follow the troubleshooting steps below:
a) Manually go through the MATLAB search path and remove the paths which have functions conflicting with built-in MATLAB functions. Execute the following command to get the list of the current search path.
>> path
The following command may help to find the source of the issue:
>> which -all <conflicting_function>
b) If you are unsure of which paths to remove or the above command displays only one line, restore the MATLAB search path to its factory-installed state by executing the following command :
>> rehash toolboxcache
>> restoredefaultpath
Notice that the above command may remove the paths that you have previously added to the MATLAB search path in order for your scripts to work. So it is advisable to save a backup copy of the current MATLAB search path before running the command.
Refer to the following link to the documentation to back up the current search path: https://www.mathworks.com/help/matlab/ref/savepath.html
If none of the above steps work, please reinstall the Computer Vision Toolbox as this issue may have been related to corrupted class hierarchies in MATLAB.
