System keeps crashing on shutdown or reboot

I am not sure what info is needed to help with this.
I am on unstable .
This seemed to start when I was building a live usb but I don’t think it has anything to do with it.
Not sure if this helps but also my keyboard is responsive so I can do a alt-fn-prtsc
I was able to shutdown once without a crash.
Here is a partial screen capture

Here is my system info

something about USB - thunderbolt & debugfs
are you in Unstable ?

yes i am

I think I fixed my problem by changing the grub line to the following:
GRUB_CMDLINE_LINUX_DEFAULT=“quiet pci=nocrs acpi=force noefi”
You can take out the quiet part if you want to see all the processes starting and stopping.

as of now I haven’t crashed on reboot or shutdown.
Not sure why this seemed to fix my issue.
I got this from this article:
