I having the exact same problem sent email to the expo team but no reply yet. I run expo credentials:manager and dont see any errors. I can build android with no issues. This is only happening with IOS builds. Trying to find urgent help on this since have schedule launch this week.
This is most likely the same issue as this one from Github, which should be resolved by upgrading the most recent version of expo-cli. Even though that did not work for @agarcia00, I recommend trying that as it has worked for most people
@agarcia00 can you share the exact command you’re running? It seems your last successful build was on April 25th, has anything changed with your iOS credentials since then? and please share the output of expo diagnostics
Is your push key being used by any apps at the moment? It might be worth clearing out the credentials we have stored for you for that app by passing the --clear-credentials flag (be aware that if you are using the push key in production, that would break push notifications for apps using the push key, so only do this if you are sure that is not the case)
Im doing further tests so far i did noticed something that may be the issue.
I clear all the certs from my dev account and allow expo to build them all. I do see the cert and the provisioning profile get created and see them in apple dev account. But even tho expo says it created the push notification cert is not listed in my dev account at all.
