PluginDebugService deletes new instances when saving

When adding a new instance to a plugin’s script and using the plugin’s context menu to save and reload, the instance disappears.
Screen Recording 2025-03-17 at 8.37.54 pm

I am unable to recreate this with a new plugin, but it consistently works with the plugin included in the private message.
This was previously mentioned in this post: PluginDebugService deleting all instances except for the script when saved & reloaded

Using MacOS, Studio version 0.664.0.6640713 (arm64)

Expected behavior

I expect the instance to stay in the same place and not be deleted.
