Fedora 41/LXDE workstation won't boot after last night's updates

Last night, I installed the latest updates on my Fedora 41/LXDE workstation. Now, the boot process always fails at the “Job plymouth-switch-root.service/start runnt File System” step, as you see in the graphic. This happens regardless of which kernel I boot up on, and also happens when I choose to boot into emergency mode. Has anyone else had this problem?
