I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @jesus-mg-ios, the crash looks to be due to a NSSecureCoding violation:

4
Foundation
-[NSCoder validateClassSupportsSecureCoding:] + 52

Another similar issue was reported in #14190. This can happen from downgrading from 11.x to 10.x. Was this downgrade done? Is this affecting a local test device or users of a published app?

[jesus-mg-ios]

No the downgrade never happened. @ncooke3
