IOS – cannot sign iOS app in XCode – in a catch 22

I have built then Archived my iOS app now need to submit to Validate and push to app store

xcode says this on main page when checkmark off Automatic signing … so do manual sign

then picked provisioning profile : prototype prod ( my app )

Status :

No signing certificate "iOS Distribution" found
No "iOS Distribution" signing certificate matching team ID "X8B4734GCE" with a private key was found.

yet when I click on Manage Certificates …
window says

iOS Distribution Certificates
iOS Distribution    john stensland      good date    Missing Private Key

then when I click on + sign and select

iOS Distribution

popup message says

You already have a current iOS Distribution certificate or a pending certificate request

then on page https://developer.apple.com/account/resources/certificates/add

iOS Distribution (App Store and Ad Hoc)
Sign your iOS app for submission to the App Store or for Ad Hoc distribution.
Maximum number of certificates generated

How do I dig myself out of this hole ?

xcode 10.3

osx 10.14.6

this is interesting

So over on developer.apple.com to Revoke an iOS Distribution certificate so I can recreate one fresh it shows me

Do you want to revoke the certificate?

Revoking this certificate will invalidate it and any related services or > provisioning profiles that use this certificate may be affected.

Is that a dangerous proposition ? I have loads of goodies in production humming away … its not clear what is implied when it says

will invalidate it and any related services

So should I Revoke this iOS Distribution Certificate and recreate one fresh ? Is this the escape hatch ?

Update yes just Revoke then create a new certificate -> download -> double click -> it gets uploaded into keychaing/xcode then it appeared in xcode -> Preferences -> Accounts -> choose Apple ID -> Team -> Manage Certificates … then xcode Automatic signing worked … moral is ignore the browser warning when revoking an iOS Distribution Certificate
