Error Finding App Store Connect Credentials
Restarting Xcode worked for me as well
Facing the same issue "Error Finding App Store Connect Credentials"
Rebooting Xcode and/or the device, sign in/out from Xcode, transporter... Nothing is working. All the certificates are Ok.
Read somewhere that the issue solved by itself, so this is something on Apple side ? System status are green.
I got "Error Finding App Store Connect Credentials" on Monterey with Xcode 14
Now on Sonoma with Xcode 15 the error message is different, any status ???
Reconnect VPN solved the issue
