Dropdown with Projects and Tags isn't working

[Nightshome]

Hi,
I have a problem with the inline-todo plugin of the plugin-bundle. I'm a huge fan of this plugin an use it every day at work.
Since i have a new notebook this special part of the plugin-bundle isn't working correct. At my old notebook, when i start a new inline-todo with @testproject +call //12.10.2024 the plugin gave me suggestions in a dropdown what projects and tags are already available. This function isn't working.
Attempts at improvement so far:

1. copy the whole joplin-desktop folder of the old notebook and paste it to the new one (C:\Users\Username.config) → no improvement (also todo-rendering to viewer isn't working)
2. paste the whole inline-todo folder of github (GitHub - SeptemberHX/joplin-plugin-bundle: Gather several plugins together into one panel with more elegant UI design!) in the plugin folder (C:\Users\Username.config\joplin-desktop\cache\com.septemberhx.pluginBundle) → no improvement (also todo-rendering to viewer isn't working)
3. clean install of joplin and the plugin bundle with the .jpl file of the old notebook → no improvement (todo-rendering to viewer works)
4. make shure, all .css, .js, .ts files in the plugin bundle folder are match the files of the old notebook → no improvement

Versions:
Joplin 3.0.15
Plugin Bundle 0.5.5
