Crash while opening apps

I have an issue with modeler 6.10.3 When I've created an app and I try to open it, it shows automatically that it doesn't work anymore. When it happens, I have two optoins: Trace the errors Shut the application down   When I choose for the first option, the error will show again. If you press "Trace erros" again, Modeler will crash Does anyone know how I can fix this problem?

This could be caused by custom widgets. You could try to remove them all and then download them one by one and test, until you find the one that upsets the app.

Check for errors in your browser console and the modeler console with each test.
