Input works only on some computers

I made a VR experience using version 4.27 that runs on a PC connected to an oculus quest 2 via link cable.

I have a few inputs with the controllers and other with the keyboard in order to be able to control the experience.

everything works as expected on 2 of my computers, but only one input is not working on another’s persons computers.

I have a key binding to the R key, and if I run the packaged app in my computers it opens a level as it should, but the other persons is reporting that nothing happens when using the letter R but all other bindings are working fine.

What could be the problem?

Could you check your .ini files for the inputs (the DefaultInput one and perhaps another ini if you use more or custom ones, like for remapping), might show what is wrong with the R key.
