Hello. This is very similar to [Latest Manjaro Update breaks Bumblebee] from a couple of days ago.
I am running kernel 5.4.58.1 , with the video-hybrid-intel-nvidia-390xx-bumblebee driver.
Before the latest Manjaro update, I could run "optirun " without any issues, but after it, (and after rebooting) I get:
> optirun glxspheres64
[19850.293957] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver
[19850.294098] [ERROR]Aborting because fallback start is disabled.
Running sudo modprobe nvidia returns:
modprobe: ERROR: could not insert 'nvidia': No such device
inxi returns:
