Certificate errors when completely valid

I'm getting a consistent error when trying to access a load of sites (sometimes even Opera's own sites) saying that the certificate is invalid.
I'm on a MacBook Air Big Sur 11.3.1, Opera is 88.0.4412.53 (arm64)
I have tried uninstalling all VPN, I've wiped all cookies through Opera, and uninstalling and reinstalling Opera.
When it links to a site that says it is not secure, I click on the "Not Secure" sign next to the webpage, and it says the Certificate is not valid. If I click on this, I get three certificates, all which come up as "valid" - so I'm not quite sure what's going on or how to solve it as I'm restricted with loads of my web access.
