Hello,
From the error message, we can see it says that the provisioning profile is not found. Since you are debugging by Hot Restart, make sure you have entered your Apple Developer account and enable automatic provisioning in the project.
But I have to say, there is a known issue being tracked at https://developercommunity.visualstudio.com/t/Cannot-load-Apple-certificates/1692185. It's related to automatic provisioning. There are temporary workarounds documented in the bug report.
So, It's suggested that you can use Manual provisioning for Xamarin.iOS, and refer to the above workarounds to import the certificate and profile.
In addition, you can connect your device with mac then pair to mac, and debug on your device. At this time, we still have to choose Manual provisioning for Xamarin.iOS.
Best Regards,
Wenyan Zhang
