Debian Linux PC stopped booting after update when external USB device is plugged in (self.linux)

EDIT 2024-02-18: Solved! JohnnyMac was right, I have no clue why, but the boot priority changed and the reboot after the update caused the issue to manifest. I have excluded the device from the bootable devices in the BIOS and it boots again.

I figured out that it was an issue with my external USB dual bay HDD enclosure. It doesn't boot when it's plugged in, even after removing it from /etc/fstab. It doesn't even reach the GRUB menu when plugged in. It only displays a blinking cursor, doesn't allow switching the terminal with CTRL + ALT + FX but does restart with CTRL + ALT + DELETE. It's able to reach emergency mode when the device isn't plugged in and is able to boot fine if it's removed /etc/fstab. Does anyone know what could be causing this issue? Everything works fine when it's plugged in after booting up the system.

EDIT: Quickly plugging it in after GRUB has loaded seems to work.

I've seen this issue before caused by buggy BIOS/UEFI implementations interacting with some USB devices where they seem to get stuck initializing. It's not clear to me how those packages could affect a problem that stops your bootloader from reaching the menu.
