Steam Overlay not working

So, I was playing LE using the Steam Overlay like normal. I use it in every game and all of my other games are still working just fine, but LE is now the only game that it doesn’t work at all. Shift+Tab stopped working and the FPS counter is not showing up anymore. I didn’t do anything, it just stopped working. I tried verifying file integrity and even reinstalling, but nothing worked. Can anyone help me?

I have the same problem. Why NOBODY from LE even trying to help?
