As a developer, when I refresh the desktop client, it breaks the back-end and the refresh never finishes

[mike-kiss]

When I'm working on the desktop client on Ubuntu, I need to test in both light and dark modes. In order for the change to take effect, I need to refresh the app with ctrl+r. When I do this, I get an error in the client and in the terminal and the refresh never completes.

This is not a huge problem but it does impede development somewhat and makes testing across different themes more difficult.
