No luck, when adding systemd.debug_shell to the end of first linux line (linux/arch/boot/x86_64/vmlinuz-linux-cachyossystemd.debug_shell) throws entirely new error (attaching below)
And when adding a space between cachyos and your line (linux/arch/boot/x86_64/vmlinuz-linux-cachyos systemd.debug_shell) throws same error which I am facing while booting normally
