Error loading [plugin]:  dlopen([plugin]: no suitable image found.  Did find:
[plugin]: code signature in [plugin] not valid for use in process using Library Validation: library load disallowed by system policy

I used to code sign and notarize Adobe InDesign plugins without any problems until last year.

I am facing an issue with code signing while building a plugin for the latest Adobe InDesign. The build is done, but when I open InDesign with the plugin, there's a problem

I use this code for codesign —> 

check_call_with_env(['codesign',

'--deep','--verify',

'--verbose','--force','--timestamp',

'-o','runtime',

'--sign', ‘XYZ Pty Ltd',

env.script_root + ‘[plugin]/Versions/A/']

, env.build_env)

I am getting below message in my Notarization report.

}

I found this error in my system log. “code signature in [app] not valid for use in process using library validation: library load disallowed by system policy”

Can anyone help me in resolving this issue? 

What steps do I need to take to fix this?

Thanks in advance for the help.
