Hi, I have a plugin based on Adobe CEP and it works normally in Photoshop 21. After I upgrade Photoshop to 23.0.0 the plugin is still under window -> extensions(legacy) but cannot be opened with "The extension could not be loaded because it was not properly signed." I tried to reinstall the plugin but the problem is still there. And I also checked this page and don't think they are the reasons for the problem. 

Can you provide more details on how to target the reason of this problem and if I want to install this plugin using the extension manager(Plugins -> Manage Plugins) how can I do it? Should I first publish the plugin in the plugins market? If so, how can I convert that CEP extension to one that can be published( the plugin contains JS files)
