iOS 14.5 breaks all Unreal apps made on Windows (and temporary workaround)

Thank you DJR85,

I deleted my old certificate and use just the new ios - certificate.
By my Personal → Certificates looks all good …
When I reimport the certificate I use the password and matched the certificate to the provision file it looks all good …
when I build I receive the same error :

LogPlayLevel: Error: IPP ERROR: Application exception: System.Security.Cryptography.CryptographicException:

and I this the problem is here with the IPhonePackager.exe :

Command failed (Result:1): C:\Program Files\Epic Games\UE_4.26\Engine\Binaries\DotNET\IOS\IPhonePackager.exe RepackageFromStage “Engine” -config Development -schemename UE4 -schemeconfig “Development” -targetname UE4Game -sign -stagedir “F:_VR\iosApp_360_AF\app 4.26\Saved\StagedBuilds\IOS” -project “F:_VR\iosApp_360_AF\app 4.26\AF_360er_App.u
project” -iterate -provision

I will try to make new certificate and provision.

Thank you very much DJR85.
