I'm sorry, I'm just now seeing your post. I don't think I ever received an email notifying me of it. I hope you were able to resolve the issue by now.
As you may have figured out by now, this was due to a certificate error in Configuration Manager version 2203. Microsoft eventually pushed out a hotfix via the configuration manager console specifically for this issue. Prior to the update being released, I copied the certificate from my configuration manager server to my local workstation and that temporarily resolved the issue for me.
I've upgraded to version 2207 since then with no issues but looking at a list of the hotfixes for ConfigMgr 2203, I'm pretty sure it was hotfix KB14480034. It looks like that update was rolled into KB14244456.
