JavaScript error after login

[bart-webleads]

🤷🏽‍♂️ Current Behavior

When I login I get this error:

A JavaScript error occurred in the main process
Uncaught Exception:
Error: Object has been destroyed
at Error (native)
at OverlayWindow.updateRenderer (/opt/Desktop Dimmer/resources/app.asar/app/scripts/main/windows/overlay-window.js:174:13)
at _.debounce (/opt/Desktop Dimmer/resources/app.asar/app/scripts/main/windows/overlay-window.js:185:47)

at tryOnTimeout (timers.js:232:11)
at Timer.listOnTimeout (timers.js:202:5)

When the errors are gone, the app works. It dims the screen. It also remembered the last setting.

🎯 Expected Behavior

I would expect to see no error when login in / starting the app.

👟 Steps to Reproduce (S2R)

In preferences enable "App Launch On Startup".
Reboot computer and login.
Please note - the app does not always print this error, sometimes it just runs fine...
