From memory what the reset actually does is invalidates the current certificate and then re-issues a new one.
So as the provisioning profile contains which certificates are valid for it, you will need to either create a new provisioning profile, or make sure you re-add the new certificate to the list of valid signing identities for it. (I’m assuming it’s a custom one, not an XCode managed one right?) Either way you’ll need to download the new profile and copy the new certificate across to your PC.
I haven’t done any iOS work recently, so I’m not sure if copying the certificate from ‘login’ to ‘System’ is still required, or whether Epic fixed the generation of the temp keychain (which was supposed to copy the certificate from your PC to sign on the mac)
Hopefully that helps
