You has deleted your .htaccess file from pub/static/.htaccess
please un-hide files on that folder if check if available, else copy it from another magento setup and copy - paste it on "pub/static/ HERE "
then follow below commands.
1) sudo chmod 777 -R var pub pub/media app/etc
2) php bin/magento setup:static-content:deploy
3) php bin/magento cache:clean
Hope this will help you,
