GRPC Dll extension file not being found by PHP on local machine

The below output appears in my CMD (windows 10) after installing (guide here):

PHP Warning:  PHP Startup: Unable to load dynamic library 'grpc' (tried: C:\php\ext\grpc (The specified module could not be found.), C:\php\ext\php_grpc.dll (The specified module could not be found.)) in Unknown on line 0 Warning: PHP Startup: Unable to load dynamic library 'grpc' (tried: C:\php\ext\grpc (The specified module could not be found.), C:\php\ext\php_grpc.dll (The specified module could not be found.)) in Unknown on line 0 ; Notes for Windows environments : ; ; - Many DLL files are located in the extensions/ (PHP 4) or ext/ (PHP 5+) ;   extension folders as well as the separate PECL DLL download (PHP 5+). ;   Be sure to appropriately set the extension_dir directive. ; ;extension=bz2 extension=curl ;extension=ffi ;extension=ftp extension=fileinfo ;extension=gd2 ;extension=gettext ;extension=gmp ;extension=intl ;extension=imap ;extension=ldap extension=mbstring ;extension=exif      ; Must be after mbstring as it depends on it ;extension=mysqli ;extension=oci8_12c  ; Use with Oracle Database 12c Instant Client ;extension=odbc extension=openssl ;extension=pdo_firebird extension=pdo_mysql ;extension=pdo_oci ;extension=pdo_odbc ;extension=pdo_pgsql extension=pdo_sqlite ;extension=pgsql ;extension=shmop extension=grpc 

I've downloaded the correct DLL version (x64) for the right PHP version (7.4) and I can even click the location cmd tries when I run it in VS code which just opens the DLL its telling me I don't have. I've also included the extension section from my php.ini as im absoltuely at a loss at this point.
