Hello I am using virtualbox 6.1.50 on Ubuntu 22.04 LTS.
I have 2 windows vm and 2 linux vm whenever I tried to run any vm I got the above issue for all 4 vms.

The first thing is that you are using an Ubuntu distribution of VirtualBox 6.1.50, not the 'official' Oracle release, That version was released by Oracle in January 2024 as a final maintenance update. It is now end-of-life and is no longer supported by Oracle; and is known not to be compatible with more recent Linux kernel updates.

You could roll-back to a supported kernel and wait for Ubuntu to get its act together; or take the better option of upgrading VirtualBox to the currently supported version. The latest version, as of July 2024, is 7.0.20 available direct from Oracle's own Download pages: https://www.virtualbox.org/wiki/Downloads and https://www.virtualbox.org/wiki/Linux_Downloads

Looks like this is specifically a Ubuntu issue because I'm running 7.0.20 and ran into this issue yesterday as well. Found this thread as a result.

Hey there,

having the same issue with following setup:

OS: Ubuntu 24.04 LTS x86_64
Kernel: 6.8.0-40-generic
Oracle VM VirtualBox VM Selector v7.0.20

I had the issue already before the upgrade with Ubuntu 23.10, but hoped it will disappear after the upgrade.

Also I found a workaround for me - I have an commercial on-access virus scanner running and when I stop this service, everything works fine (I informed the support).

Update: The issue was resolved by the virus scanner company and the vm's can be started without errors.

That's good to know; and something else to check for. We don't seem to see many questions/reports coming from Linux users who 'admit to' using Anti-virus/Security scanning software.
