Windows 10 pro 64-bit (version 1803)
graphql-playground-electron-setup-1.5.6.exe
Installed for the first time.
Selected online movie database URL, the query window opened successfully.
After that, I clicked on some history link (i do not remember and can not reproduce as not able to use the app thereafter) and the screen went blank, with only Navigation on top. Can not go to the query screen again. Clicking any item in the navigation, the below screen remains blank. I closed and opened the app again, selected movie database url again, the blank screen with navigation appears.
After application re-installation also (used Wise uninstaller to remove any residual config files), the same blank screen appears with navigation, making application impossible to use.
The screencapture gif is attached.

@ajit555 I run into that same issue on my mac. Clearing my graphql playground local storage and graphql playground cache fixed it for me. You could try that as a workaround for now, until this bug is fixed.
@operolim I would try that and reply if it fixed. Sorry for late reply as got busy in other work.
I had the same issue on Mac with v1.5.6, though seems fixed in v1.5.8. Can anyone else confirm?
Yes, the issue is fixed on Windows 10 after installing v1.5.8 (graphql-playground-electron-setup-1.5.8.exe).
However, in application>settings, it is showing version as "1.6.6"
@ajit555 You can read more about it https://github.com/prismagraphql/graphql-playground/issues/662
It seems that this is fixed in the latest version. Please let me know if this is still a problem for you, then we reopen this issue.
