bbswitch does not work on boot

[rhysperry111]

Hi, if I try to load bbswitch automatically (by creating an entry in /etc/modules-load.d/) my system fails to boot. It just hangs with the HP logo and does not respond to anything (even SysRq keys)
If it inserted after boot (through modprobe) it seems to work perfectly fine.
Here is the journal from a failed boot:

I am using bbswitch-zen from the AUR (no DKMS)

I use wayland

I do not use my nVidia gpu (only intel), do not have the proprietary driver installed and I have blacklisted nouveau.
