Error on Reset Layout in Studio

Dear All,
Could someone clarify the solution above wherein it is suggested to rename the file. Which file should be renamed?

I am trying to delete a custom module. Upon reading the posts in the forum, seems like the custom modules have to be reset (i.e. relationships should be deleted) before the module is deleted.

Could someone please help me out? I am getting the error: DeployedMetaDataImplementation->getFileName(): View Array is not recognized

Thanking you in advance.

Best,
Jori
