HotKey Setting Bug - Unable to assign new hotkeys

[Roundlay]

Suddenly, 2.0.140 has stopped allowing me to assign custom keyboard hotkeys.

Now, I'm only able to assign a mouse hotkey (Mouse Button Left, Mouse Button Right, Mouse Button X1, etc.)

No keyboard input is recognised in the HotKey fields (I can left click a HotKey field in order to change it, but no keyboard keys are registered).

I've attached my environment information file.
