SecCertificateCopyKey does not work on some iOS 14 Version and SecKeyVerifySignature at all

`SecCertificateCopyKey` returns always nil on iOS 14.4.0, 14.4.1 and 14.4.2 but on iOS 13 and 14.1 works fine.

Is there a workaround for this ?

`SecKeyVerifySignature` with algorithm `ecdsaSignatureMessageX962SHA384` does not work properly (has been tested on devices with iOS 13 and 14).

is this already known?

Any workaround?
