Impossible to see inspector/scene tree

Hi. I tried to create new map but I have no inspector / scene tree, even if tried to restart beamng & computer many tries. I aslo tried many things directly on beamng but no result. Weirdly, it seems to works in safe mode and not in "normal" mode even after I deleted all my mods (This is why im posting, plus because safe mods don't keep settings (ex: kmph or mph etc.) and im not sure I can save maps with safe mode). If anyone knows how to fix it please tell me ^^. PS : Im not good at english, sorry if there is a lot of errors.

 

In the top bar, go to layout, and then select default, it should appear.

 

It works, thanks. Its weird because I never go there..
