Xcode 13.3: "not valid for use" error

[cliftonlabrum]

Ever since upgrading to Xcode 13.3 and accepting the recommended project settings for my app, this package is no longer working. Here's the error I get:

dyld[72581]: Library not loaded: @rpath/MailCore.framework/Versions/A/MailCore
code signature in <...> '/Users/.../Library/Developer/Xcode/DerivedData/MyApp-gzqkbbrjqdkwkyfdvbgtuywdvkjh/Build/Products/Debug/MailCore.framework/Versions/A/MailCore' not valid for use in process: mapped file has no Team ID and is not a platform binary (signed with custom identity or adhoc?)

I tried deleting and reinstalling the package to no avail. Has anyone else run into this?

Same here. Switching the macOS Signing Certificate for my app under Target > Signing & Capabilities from Sign to Run Locally to Development did the trick.
