I have tried this but the problem persists after a reboot.
UPDATE: I have tested this again. I forgot to mention that it's even worse with an /etc/modules-load.d/uinput.conf. After a reboot, I get the same error as before but a sudo modprobe uinput doesn't help anymore. I have to run sudo modprobe -r uinput; sudo modprobe uinput to fix the openFd: permission denied error (temporarily).
This fixes it. Thank you! Do you know why I need
TAG+="uaccess"now but didn't need it in the past?
