Why some of the letters can not be written on In Design ?

Yesterday I couldn't use my 'b' and today I can not use 's' on a new document the thing is 'b' still doesn't work on the old document. I checked if it is possible to be from the fonts, but the problem is not there.

Are you sure it isn't your keyboard? Can you use those keys in other programs?

[Vanya21937682rm7w]

Yes, I am completely sure, because as you can read they are working at the tme I'm texting.And they are working on every other program, but not InDesign.

I even updated the program and opened the files again but still, those two letters didn't work. I have no idea what to do.
