As far as I know, the prefer client for OpenVPN AS is now OpenVPN Connect v3 which can be found here:

If you want to continue to use OpenVPN Community Edition and OpenVPN-GUI, I recommend upgrading to at least version 2.4.11 or higher. It can be found here:

For OpenVPN CE, may also want to try putting the configuration file in:
\Users\$USERNAME\OpenVPN\config
Lastly, you may also want to consider upgrading to OpenVPN Access Server version 2.9.0 which modifies the server-locked profiles to be compatible with OpenVPN Community Edition.
