Wireless Certificate Failure

Sometimes when we image a machine to our network on Windows 11, they fail to connect properly to our wireless.

We have our main wireless, and then a second wireless that is essentially a visitor one. You can connect the laptop to the second one with no issues (need to input a password), but when trying to connect it to the main one (should just authenticate without a password if imaged), it says 'unable to connect to this network'. We push the certificate out through GPO, and  as I've mentioned, it does it intermittently on different devices so we don't feel it is a problem with the GPO itself?

- we're just wondering if anyone else has had similar issues and if they have managed to get around them?
