v86d has been dropped from Manjaro repositories and is no longer required for mhwd
Re: Unstable Update MHWD disussion
If pamac GUI options Enable AUR support and Check for updates are enabled, users should check the package list before agreeing to update and un-check AUR packages
If Check for updates option is not enabled, pamac GUI would only update repository packages
After this update mhwd was not working but no issues with mhwd-kernel or mhwd-gpu
$ mhwd -l
Error: Following directories do not exist:
> /var/lib/mhwd/db/usb
> /var/lib/mhwd/local/usb
Solved by creating directories /var/lib/mhwd/db/usb and /var/lib/mhwd/local/usb
