I am getting a BSOD when starting Bitdefender VPN

The message reads KMODE EXCEPTION NOT HANDLED ndis.sys

The minidump pointed the Virtualbox (VBoxNetLwf.sys). But after upgrading Virtualbox and eventually deinstalling the problem remains, but now pointing to npcap.sys.

I reinstalled Bitdefender VPN, but that did not help.

At first installation of Bitdefender 2 weeks ago it worked fine.

Any suggestions?
