windows 10 installation throwing error every folder change

every directory change thorws an error.
I tried to reinstall fman, without any success. (Installation path was C:\Users\andre\AppData\Local\fman)

Maybe because the C:\Users\andre\AppData\Local\fman\Versions\1.7.0 is still there after removal of the app

I tried a second install with deleting the folder inbeween.
No success

The details of one error message

DirectoryPaneListener 'GoToListener' raised error.

Start with core/commands/goto.py at on_path_changed, then inspect fman/impl/plugins/config.py and the load_json call for Visited Paths.json. Reproduce the error by changing directories on Windows 10 and trace how the empty or invalid JSON is handled. Done means directory changes no longer raise this JSONDecodeError.
