Usually, its easy to chroot into your system.
Use you live-usb again and only type at a console manjaro-chroot -a
which will automatically look for your installed system.
If that doesnt work, you either have to install manjaro-tools or manually chroot like
with the steps described here.
Then you will dropped into your enviroment, and can see, if plymouth is installed and if you can remove it, like it is described at this post
and then install another Kernel like 6.1 or 6.6.
An other may quicker way is to edit your grub during startup with e, when you are on the main screen from grub, where you pick a Kernel.
Mark it, press e, then just delete anything with plymouth at the line (since it seems you have no quiet or splash at the parameters, if you have, just simple remove that), then continue booting with F10.
This changes will only be temporary, means, you cant do anything wrong, when you delete there something, and it doesnt work, because your old predefined options will be loaded again at the next boot, if you dont change anything at the system.
I am not sure, what you have installed, because it shows 2 different Kernels, but its not that importend right now, because removing plymouth should work anyway.
One of this things should work, else, i found by one from your errors another page, that this error is a sign, that the grub installation is kinda faulty. But when it now works only by removing plymouth, it shall be ok.
If not, then there is at the lower part from the restore grub wiki above a description, how you can install grub again, in your case, it would be nvme0n1p1, since its already an efi partition.
