How to fix

Step 1

Set your autoload section in the root’s composer.json file as in Magento 2.3.2:

"autoload": {
    "psr-4": {
        "Magento\\Framework\\": "lib/internal/Magento/Framework/",
        "Magento\\Setup\\": "setup/src/Magento/Setup/",
        "Magento\\": "app/code/Magento/",
        "Zend\\Mvc\\Controller\\": "setup/src/Zend/Mvc/Controller/"
    },
    "psr-0": {
        "": [
            "app/code/",
            "generated/code/"
        ]
    },
    "files": [
        "app/etc/NonComposerComponentRegistration.php"
    ],
    "exclude-from-classmap": [
        "**/dev/**",

        "**/Test/**"
