Hi @Anees Magento,
Make sure that ou have correct permissions on the server.
Try the following command once if permission are incorrect:
find . -type d -exec chmod 755 {} \; && find . -type f -exec chmod 644 {} \; && chmod u+x bin/magento
You can use sudo as well.
Then executes the following commands once in the sequence.
chmod -R 0777 var/ pub/ generated/
rm -rf var/cache/* var/view_preprocessed/* generated/* pub/static/*
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush
php bin/magento indexer:reindex
chmod -R 0777 var/ pub/ generated/
I hope it will help you!
