"Module aw-watcher-window quit unexpectedly."

I use the ActivityWatch app to track the time that I spend on the computer. I am running v0.12.2 which is the latest version. When I restart my computer, it displays an error message. The error message says, "Module aw-watcher-window quit unexpectedly." How can I prevent this error from occurring? Please find attached a screenshot of the error message. I also reported this issue to the developer on GitHub .
