(Level) Blueprints won't show code

Hi,
I am not able to see the code in my level

blueprints any more. The window opens but remains empty.

What I did so far:

I completly reinstalled the launcher and the engine.
I reset the project to my last commit.
I cleaned the project from any new files.
I pressed Window → Reset Layouts…
I created an entirely new project
The project compiles fine and the build is starting.
I deleted my temp folders with ccleaner.

What else could be done to get it back working?

What may have caused the problem was adding the [Gameanalytics][2] plugin through the market place and added the session start code to the level blueprint. I also enabled it in the plugins menu and then set the keys for the plugin.

EDIT: After deleting the folders under Users\AppData and reinstalling the engine it worked again. What I did next was to enable the analytics plugin → then I installed the GameAnalytics Plugin from the market place → restarted the engine → Added the keys to the project settings for the GameAnalytics Plugin → restarted the engine and inserted the code to start / stop the sessions and post some custom events. → This is the step where it broke I closed the engine and copied these two lines into the DefaultEngine.ini.

[Analytics]
ProviderModuleName=GameAnalytics

After restarting the engine Blueprints are empty again. And the right mouseclick does not allow to move the camera anymore. It also extended to all other Blueprints. After deleting the users folders again I can see the blueprints again but the mousbutton remains disabled.

Hope someone can help.

From what I understand, the Game Analytics is the cause of the problem.
You should contact the plugin maker:

Hi,

This bug should finally be fixed in the latest release of GameAnalytics (v2.6.1). It can be downloaded from here: https://github.com/GameAnalytics/GA-SDK-UNREAL/archive/master.zip or it will of course also be available on Marketplace as soon as the new version has been approved.

Thanks,
