After Ubuntu kernel upgrade in Virtual Box Genymotion Virtual machine Host-Only Adapter is missing, attempt to create a new one is unsuccessful

I am using Ubuntu 20.04 My Virtual Box was running perfectly fine. But then I upgraded my kernel and rebooted the computer.

Now when I am trying to start my Virtual Machine I am getting the following error -

Could not start the machine Samsung Galaxy S10 because the following physical network interfaces were not found:

vboxnet3 (adapter 1)

You can either change the machine's network settings or stop the machine.

If I click on Change Network Settings, the under Host-Only Adapter there is no Name that can be selected.

Now, if I click on cancel I get the following error -

Failed to open a session for the virtual machine Samsung Galaxy S10.

Nonexistent host networking interface, name 'vboxnet3' (VERR_INTERNAL_ERROR).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

If I go to File -> Preferences -> Network there is a tab having only NAT network and no Host-Only Adapter tab.

If I go to File -> Host Network Manager -> Create a new network vboxnet0 -> Enable -> Properties -> Configure Adapter Automatically -> Apply

I am getting the following error -

Failed to save host network interface parameter.

Callee RC: NS_ERROR_NOT_IMPLEMENTED (0x80004001)

At this point under the Virtual Machine -> Settings -> Network, below Host-Only Adapter the Name vboxnet0 is present, but still the problem persists.

I have also tried from terminal -

sudo /sbin/vboxconfig

and got the following output -

vboxdrv.sh: Stopping VirtualBox services.
depmod: WARNING: could not open modules.order at /lib/modules/5.8.0-36-generic: No such file or directory
depmod: WARNING: could not open modules.builtin at /lib/modules/5.8.0-36-generic: No such file or directory
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.

UPDATE:

My Virtual Machine Samsung Galaxy S10 has not been created directly from Virtual Box but by Genymotion Android Emulator Creator.

The directory VirtualMachines under my home directory is empty. The Virtual Machine is rather present in the location ~/.Genymobile/Genymotion/deployed/Samsung Galaxy S10

I finally solved the problem.

In terminal I had to run -

sudo /sbin/vboxconfig

Then in Virtual Machine I had to do -

If I go to File -> Host Network Manager -> Create a new network vboxnet0 -> Enable -> Properties -> Configure Adapter Automatically -> Apply

and ignore any error prompt.

Then in file manager I had to go to

~/.Genymobile/Genymotion/deployed/Samsung Galaxy S10

Then I double clicked on the icon -

Samsung Galaxy S10.vbox

A terminal opened and did some job.

Then I closed the terminal. After this action everything was working fine and I could start my Virtual Machine from Genymotion successfully.
