I can only select with shift, what happened?

Hello. Suddenly I became only able to select anything in edit mode with shift + right click. If I only press right click it doesn’t make anything. It’s a bit boring the need to press shift key everytime I wan’t to select anything. I’ve searched in the options and I can’t find anything that fixes this. I’ve already changed from right to click to left click and back on to right click to see if it solves but no lucky at all.

Basically, the right mouse click itself doesn’t work, it always needs the shift key to be pressed like if I was going to multiple select even if I want to select only 1 thing,

What did you change ?

File / Load Factory Settings then append the scene from any blend file you want to continue to use

I don’t know but after reseting factory settings this happened to me again. The only thing I notice that is different from usual is when I press X to delete instead of appearing only Faces in the submenu, it appears Faces and Right Mouse in front of that. Weird.
