Have been using input-remapper for months now, simple Razer mouse with 2 side buttons, mapping them to shift_L and ctrl_l for quick action bar usage on MMOs. auto-loads on login/reboot and no issues until today.
"ujust-update" today was all but 2 chunks, and afterwards input-remapper appears to be "working" except that in the preset you can see it's stuck in "Starting injection...". It sees my inputs, preset adds remaps just fine - just stuck on "injecting".
"sudo pkill -f input-remapper" from the internet did not work
tried deleting ~/.config/input-remapper-2/ folder as well
