Delete Custom module

I am new to magento development, made a custom module
Vendor: Scandiweb
Module: Scandiweb_Test
The naming convention is not correct so I decided to delete it, I can’t run module:uninstall because its not installed from composer, I deleted the directory and the occurance in app/etc/config also checked db setup_modules, the module name is not present.

Now whatever I do I am getting this error:
How do I solve this?

PHP Warning: require_once(/app/code/Scandiweb/Scandiweb_Test/registration.php): Failed to open stream: No such file or directory in /app/etc/NonComposerComponentRegistration.php on line 29
