Virtualbox 6.1.36 host on Ubuntu 22.04 5.15.47

[KenUnix]

After Ubuntu did an upgrade to 5.15.0-47 kernel Virtualbox faulted running Windows VMs'. They would start then reboot again and again.

After research I found the answer was to upgrade Virtualbox to Version 6.1.36 r152435 (Qt5.15.3). After doing that I am unable to run
any VM's.

I get the message Kernel driver not installed (rc=2908) followed by
'/sbin/vboxconfig' and If your system has EFI secure boot enabled you may also need to sign the kernel modules vboxdrv, vboxnetflt
vboxnetadp and vboxpci. Where suplib0sinit what : 3.

Everything worked perfectly before this. My system is Ubuntu 22.04 64 bit on a Dell 5755 laptop.

Any help would be appreciated.
