Network bridge causing virtual guest to crash on boot

Hi, I was using network bridge mode for virtual adapter in all my virtual guests to access internet, but it doesn't work now. Whichever guest I try to boot, raises this error on boot attempt

Nepodařilo se otevřít sezení k virtuálnímu počítači Windows 10.

Failed to open/create the internal network 'HostInterfaceNetworking-Qualcomm Atheros AR8171/8175 PCI-E Gigabit Ethernet Controller (NDIS 6.30)' (VERR_INTNET_FLT_IF_NOT_FOUND).

Failed to attach the network LUN (VERR_INTNET_FLT_IF_NOT_FOUND).

Návratový kód: E_FAIL (0x80004005)

If I change the mode from network bridge to NAT, guests do boot and have internet access as well. I reviewed that the virtual adapter is attached to existing hardware card and found nothing invalid. The bridge mode did work for me previously with most probably the exactly same setting, so I would ask what went wrong, or how do I resolve the issue. Other than that, I notice there's a virtual hosted network at 192.168.56.1 maintained by VBox. Do I need to grant a firewall permission to this network?

See Virtualbox Networks: In Pictures

The 192.168.56.1 network is the default Host-Only network. It is not used to grant internet access to the VM.

If your Windows host OS has gone through a major update, Virtualbox might need an uninstall a reboot and a reinstall via right-click-Run-As-Administrator.

There's no major OS update. Though I fully uninstalled VirtualBox Host Only Ethernet Adapter + VirtualBox software and as expected the error from OP still occurs with Network Bridge regardless to which physical card I attach it. Is there a way to fully reset network settings on virtual machine and setup from scratch?

Something has damaged Virtualbox's ability to Bridge. The uninstall & reinstall process shown above may fix Virtualbox.

If you are doing a reinstall of VirtualBox, there is an option in the installer to not install the host only adapter if you don't need it.

At Windows start menu, type Virtual Network Editor (it needs to be run as Admin) and see if there is something messed up! Also check if all is well in the Turn Windows features on or off.
You could also perform repair to your Windows:
Run in Admin CMD

C:\WINDOWS\system32>chkdsk c: /b /f /v /x /scan
Also: DISM may not able to fix files even with the path resolved without using these commands before it.
C:\WINDOWS\system32>DISM /Online /Cleanup-Image /StartComponentCleanup
C:\WINDOWS\system32>DISM /Online /Cleanup-Image /AnalyzeComponentStore
C:\WINDOWS\system32>DISM /Online /Cleanup-Image /RestoreHealth
C:\WINDOWS\system32>SFC /SCANNOW
