Hi everyone,
If you go to https://playground.babylonjs.com No mouse or keyboard control anymore 
Best wishes
Joe
It seems it was something with FreeCamera, playgrounds with ArcRotateCamera were working fine.
Couple minutes later I opened it again and it is fine now for FreeCamera too.
Huh, weird. It is working for me again, too 
As for me, I lost the keyboard control for the default PG with FreeCamera quite a long time ago. Seems that after some improvements it was broken and, since the bug is rare (still there were several mentions about it at the forum), it cannot be fixed.
