Since the vendor directory is generated automatically, I would try deleting the vendor directory and running composer install again. Also magento setup:upgrade once that happens (confirm database is up to data with package versions). magento cache:clean and reload your store front.

Beyond that, I would review the steps for creating admin configuration entries.
