Running v1.1.0 on Win10 21H2 :
Certify.exe find /vulnerable

results in the following error message:

[!] Unhandled Certify exception:

Big bump to this one.

8b898b7 this was the break, and specifically "template.ApplicationPolicies".

When enumerating, it's failing on a null value in mspki-certificate-application-policy.

I also receive this error while searching for vulnerable templates on Windows Server 2019
