Somehow the code checking for must be graphics object got corrupted. You will need to reinstall matlab unless you can restore the file from backup.

You should probably not be cd to the matlab installation directory

how can i restore the file from backup

[Walter Roberson]

Which backup system did you configure on your Windows system? You need to have specifically configured a backup program first.

Microsoft tends to recommend using File History these days, but File History is usually not configured to cover program installation directories. https://www.handyrecovery.com/windows-backup-and-restore/ .

can u plz tell me what files do i need for backup and how to do it

[Walter Roberson]

C:\Program Files\MATLAB\R2020a\toolbox\matlab\validators\+matlab\+internal\+validation\mustBeValidGraphicsObject.m

is the name of the file you need to restore.

I cannot tell you how to do the restore until you tell me which backup program you configured for your system.

MATLAB does not automatically back up files, and MS Windows does not automatically back up files either (not without being configured.)

Try just uninstalling and reinstalling MATLAB.

Then I wouldn't make my projects folder under the MATLAB 2020 folder like you did. I'd just have a separate folder like D:\MATLAB Projects or something like that. In there have all your scripts, or have subfolders for projects if you have a bunch of files that are all related to one specific project, like D:\MATLAB Projects\FaceRecognition or D:\MATLAB Projects\Fruit Identification or whatever.
