Try this all step it will be useful for you

1.Clear the generated files: Run the following command from your Magento root directory to clean up the generated files.

php bin/magento setup:di:compile
php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy -f

2.Flush the cache: Run the following command to clear the cache.

php bin/magento cache:flush

3.Remove generated directories: Delete the contents of the generated and var/cache directories. You can do this manually or by running the following commands.

  rm -rf generated/*
  rm -rf var/cache/*

4.Check for conflicting modules: Ensure that there are no conflicting modules or extensions installed. Disable any recently installed or updated extensions and check if the error persists.

5.Update dependencies: Make sure your Magento installation has all the required dependencies and they are up to date

Run the following command to update the dependencies:

  composer update

6.Verify PHP version and extensions: Confirm that your PHP version is compatible with Magento 2.4.2

7.Check file permissions: Ensure that the file permissions are set correctly for your Magento installation.

If the above steps don't resolve the issue, please provide more details about your Magento setup, including any customizations or extensions you have installed.

Try deleting the vendor directory using the command rm -rf ./vendor, then run composer install, and finally, attempt to follow the advice provided in the previous answer.
