There is a fetch error:

The 'Access-Control-Allow-Origin' header contains multiple values '*, *', but only one is allowed. Have the server send the header with a valid value, or, if an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Maybe remove

Header set Access-Control-Allow-Origin "*"

from .htaccess
