I was testing the app I'm working on and the screen was all gray with this sad face.

At first, I thought it was just an internet connection cause a sudden power surge restarted my internet modem.
So once I cleared that up, I tried again and it was smooth until it showed again.
Unfortunately, I was not running the Monitor tool so I am not sure where to start.
What I have tried so far:
- Try to use app as usual
- Cut off the internet
To anyone who has experienced this, what have you found to be the cause for your case?
