I'm not sure what your description means. Can you be more specific?

[reducedcarpet]

I had an app running on a physical device, initiated through android studio using the profiler button. And then using the terminal in android studio, I did a command line flutter clean. It was at this point I thought android studio was about to crash, but instead it popped up a window with the above error in it. It said to copy the above and paste it into the error report. And then it did not crash, which was nice.

[stevemessick]

Thanks for the update! The cmd line flutter clean was what I needed.
