After kernel update: dracut /dev/root does not exist

[GandalfGuy]

Hi there,
I'm new to Gentoo and installed it a few days ago. Everything was working fine (I was able to boot and setup everything) until I decided to upgrade the Kernel. When I reboot it just hangs and after waiting (for the dracut timeout), I get the message: dracut Warning: /dev/nvme0n1p5 does not exist (my root partition), and then I get dropped in a dracut recovery shell.

I am using a distributed Kernel and Systemd boot. First I thought that there are problems with the initramfs, but I think it's setup correctly, but I'm not quite sure how I can confirm this.
This is my systemd boot entry.

Please try to use the PARTUUID or UUID for your root=. The /dev/nvme* paths are not stable, they may change if your firmware for whatever reason initializes the disks in a different order.

I tried both UUID and PARTUUID but the issue persists.
