MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT HSTS in https site

I downloaded a project on localhost via bitbucket, I set up a virtual host but I have an error on each browser that the certificate is self-signed. I created the certificate in xampp and added it to trusted certificates in the chrome / windows 10 settings and unfortunately I still have the same error. The project is on laravel 5 and in env file I set the http and APP_DEV domain to local.

my virtual host:

<VirtualHost *:443>
    DocumentRoot "E:\xampp\htdocs\project\public"
    ServerName project.app
    SSLEngine On
    SSLCertificateFile "E:/xampp/apache/conf/ssl.crt/server.crt"
    SSLCertificateKeyFile "E:/xampp/apache/conf/ssl.key/server.key"
    <Directory "E:\xampp\htdocs\project\public">
    Order allow,deny
    Allow from all
    </Directory>
</VirtualHost>

I would like to run a project via virtual host on laravel 5. Unfortunately, I still have the error HSTS MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT on firefox on chrome and NET :: ERR_CERT_COMMON_NAME_INVALID. I will add that I only want to run the project locally on the localhost, therefore no certificate is needed here, but the browser blocks
