How, can I remove this error and display grid?

Answer 1

Go to on this below path :

setup/src/Magento/Setup/Model/Grid/Module.php

Go to line 181 and replace this below code :

$item['moduleName'] = isset($item['moduleName']) ? $item['moduleName'] : $this->packageInfo->getModuleName($item['name']);

Clean cache and then refresh module manager page.
