Is there something I'm missing here? I've tried MacOS and Linux. Also, if I switch it out for a non-existent CredID, it errors out in the same way.

Looking closer at the CTAP 2.1 spec, it looks like authenticators that have the credentialMgmtPreview optionID and FIDO_2_1_PRE version BUT don't have the FIDO_2_1 version can't do what I'm doing.

This is because "FIDO_2_1_PRE" authenticators, unlike "FIDO_2_1_PRE" authenticators, do not support the authenticatorCredentialManagement (0x0A) command. Instead, they support Prototype authenticatorCredentialManagement (0x41). The Prototype authenticatorCredentialManagement does not have the subcommand updateUserInformation (0x07) that the authenticatorCredentialManagement (0x0A) command has.

I apologize to anyone who looked into this due to my negligence.
