Unhandled Exception Error, when cancelling an image generating

[EReis0]

I started receiving this Error after upgrading to 1.5.0 while pressing the cancel button to stop the current generation process. I did get the error while working with a loaded image and just on a pure prompt image generation.

This is a fatal error which it's required to close and relaunch to proceed with the project.
