[ID-4265726]Error during shutdown UXP plugin (InDesign 20.4.1)
If you try to access indesign.app when shutting down a plugin, an error is thrown and causes InDesign to freeze. Specifically, in the lifecycle hook »hide« and »destroy«.

The fix of the issue is now available in the latest InDesign 2025(v20.5.0.048). We recommend you upgrade to the latest version for the fix.
If you are unable to see the update, go to the Creative Cloud application click on the context menu on the top right, and click on Check for App Updates.

The same behavior occurs when you uninstall the plugin via the Creative Cloud app. InDesign froze and you can no longer close the app.
A video is attached. You can't see the spinning beach ball in the video, but it spins continuously.
In the link above you can download a sample plugin that shows this behavior. You can neither attach a ZIP file nor a ccx file here. How can I send you the plugin file?

Thank you for reporting this issue.
Could you please confirm whether the freezing occurs when the user disable the plugin from the Creative Cloud App?
If the issue also happens with a UDT as well, please provide the plugin that includes the manifest.json file and video illustrating the issue.
Thanks,
