 This error message indicates that the code signature for a library or framework used by your application is not valid for use with Apple's Library Validation feature. Library Validation is a security feature introduced in macOS Mojave that verifies the integrity of code signatures for system libraries and frameworks.

There are a few possible reasons why you might be seeing this error message:

The library or framework you are using is not signed properly. To fix this, you may need to obtain a properly signed version of the library or framework from the developer.

The library or framework you are using is signed with an older version of Apple's code signing certificate that is no longer trusted. To fix this, you may need to obtain an updated version of the library or framework that is signed with a newer code signing certificate.

Your application is running on an older version of macOS that does not support Library Validation. If this is the case, you may need to upgrade your macOS version to a newer one that supports Library Validation.

To troubleshoot this issue further, you can try the following steps:

Check the code signing status of the library or framework using the codesign command. For example, you can use the following command to check the code signing status of a framework:

codesign -dvvv /path/to/framework

If the code signature is not valid, try obtaining a properly signed version of the library or framework from the developer.

If the code signature is valid, try running your application on a newer version of macOS that supports Library Validation.

If none of the above steps resolve the issue, you may need to consult with the developer of the library or framework for further assistance.
