remix os keymapping problem

hi guys i just recently tried the new update for remix os 2.0.402 it was smooth as expected but i have a problem the keymapping is still not working for me i am on 1024X768 resolution and i am getting this error from the built in keymapping tool on remix itself is there anyway around here to fix this like cfg files to tinker just to make it work or like tincore because tincore still does not work
