[Solved] Arch boot freeze, no emergency terminal

So I tried to boot into arch today after setting up some basic python stuff with emacs like a week ago
and now it doesn't boot correctly. I think I installed black or flake8 or something.

I wish I could provide more logs however it doesn't pass me into the emergency terminal and I can't
switch to a (Alt-F{n}) terminal.

I saw that the wiki said you can use (Ctrl-S) to pause the terminal output but it didn't work.
I assume that's only for after the machine boots.

I tried to use my phone to record a video of them but the messages fly to quickly. Either way, this method
to put it lightly is much less than ideal.

=================================================================================

I was able to capture at least one failure message however:

[FAILED] Failed to start Load Kernel Modules
See "systemctl status systemd-modules-load.service" for details

Afterwards, I see that it can load kernel variables, etc. It then starts to look at my USB devices at which
point it freezes.

I know that the above messages are largely useless they lack context.
I saw there are similar posts on these forums except they are able to get access to a terminal of some
sort.

==================================================================================

So I guess step 1 to is to get the complete logs.

I still have the USB I flashed Arch onto.
I didn't want to use it without having direction in case I make the problem worse.

Does someone know how to get logs without being able to get a 'native' terminal going?

Re: [Solved] Arch boot freeze, no emergency terminal

Use your bootable USB.

You need to boot on live mode, mount your partitions and chroot.

After that, you can post a journal log using a pastebin service.

If the problem was installing something, post a pacman log, too. (/var/pacman/pacman.log)

Do you have an nvidia chip?
Add

ibt=off

to the kernel parameters.

I do have an NVIDIA graphics card. I use refind instead of grub. Do you know what file I would need to take a look at to verify 'ibt=off'?

Closing Post.

Thanks @Seth

Adding ''ibt=off" was the correct fix.

Edit:
Added kernel parameter by  pressing + twice in the refind boot loader and appended "ibt=off" to the parameters.
Afterwards I edited /boot/refind_linux.conf with the same changes in order for them to persist.
