Keyboard layout changed in RStudio but nowhere else

Question

Since yesterday I am encountering this strange error in RStudio. The keyboard-layout has changed completely. However, only in RStudio and nowhere else.

y became the z button
- became /
( became *
) became (
= became )
? became _

how can I resolve this issue? I am running RStudio 1.1.383 and ran the sessionInfo() command. I got this output in the consol:

This happened to me too and I followed the instructions here. I never did it on purpose so I will have to wait and see if it happens again but hopefully that helps.
