Cannot rebind sprint from shift to backslash EU Keyboard

I use ESDF instead of WSAD to move. This means that I rest my pinkie finger on backslash instead of shift.

I have bound this key in multiple other games so it should be trivial to add to the list.

tbh I don’t know why all buttons are not re-bindable apart from Esc considering accessibility needs

I have the same issue. I use WASD but also use backslash on EU keyboard to Sprint. It works on all my other games and I hate it doesent work here.
