EQS Query blank screen

I want to use the environmental Query but always the result is this image :

I have try the workaround from Mieszko :
DefaultEngine.Ini :
[EnvironmentQueryEd]
EnableEnvironmentQueryEd=true
and of course , I have activate the experimental feature.
If someone knows another workaround I will be happy !

thanks in advance community.

haha I feel so dumb, this is how I resolv this! men…
