Windows VBox dev. build 6.1.19 142917 (and 142946) host won't start VMs but 6.1.19 142777 does

Dunno if anyone is running up against this?
Virtual Box Dev Build 6.1.19 142917 won't start any guest VMs with me but build 142777 (the prior dev build) works fine.
I've raised a bug but just wondered if others had seen it?

Details (I've not added the hardening log, unless others think it's relevant - but I've added it to the bug ticket):

Bug report:

Am running Windows 8.1 Pro x64 fully patched (build 9600.19941).
Symantec Endpoint Protection: Version: 14.0.3929.1200 (14.0.3929.1200.105 to be exact)

With developer build Virtual Box 6.1.19 142917, I receive the following (or similar) when trying to start any VM
(XP 32 bit, but also same for a 64 bit Windows 10 guest and 32 bit Windows 7 guests)
The previous developer build: 6.1.19 142777 was fine.
The only change is the build of Virtual Box, and indeed reverting back from 142917 to 142777 fixes the problem.

Error messages:

Failed to open a session for the virtual machine XP.

The virtual machine 'XP' has terminated unexpectedly during startup with exit code 1 (0x1). More details may be available in 'C:\VBoxMachines\XP\Logs\VBoxHardening.log'.

Result Code: E_FAIL (0x80004005)
Component: MachineWrap
Interface: IMachine {85632c68-b5bb-4316-a900-5eb28d3413df}

Note: The newer development build: 6.1.19 142946 also shows the same symptoms on my system and will not start guest VMs.

Note to anyone seeing this. This has now been diagnosed to root cause and acknowledged as a bug by Virtual Box staff and relates to certificate signing issues.
See:

https://www.virtualbox.org/ticket/20226

for details.
