SOLVED Steam interface does not launch

Hello.

I've followed every step on the installation guide (download via steam, download and paste celeste's content in the folder, let the celeste gui patch my game and used the steam helper to make it launchable via steam).

When I do launch the game via steam, it starts the celeste launcher (which I assume its normal), but when I do login there and launch the game via that celeste launcher, it does without including the steam's interface (shift+tab does nothing)

Any clues on why this is happening?

 

You can mark it as solved.
For any reason. after many things I did. now it magically works.
It shouldn't have nothing to do with, but I did run the game in diagnostic mode (nothing happnd), then disabled that mode and run the game. I did also run an extra game scan just in case.

Anyway, thanks for the help ^^
