Kernel panic - not syncing: No working init found. Help please?

Latest response

I have a RHEL 8.8 (Ootpa) VM we perform our patch testing on to prior to ohysical machine. To update I performed:

dnf update --nobest -y

On reboot I receive:
failed to to execute /init (error -2)
Kernel panic - not syncing: No working init found. Try passing init= option to kernel. CPU: 1 PID 1 Comm: swapper/0 Not tainted 4.18.0-513.9.1.el8_9x86_64
Hardware name: VMware, Inc VMware7,1440BX Desktop Reference Platform, BIOS VMW71.00V211004320B64.2301110304

I attempted to remove old kernels using yum remove --oldinstallonly prior to running dnf update to resolve conflicts but that did not help.
