Possibly, but we'd need to see the exact error message.

OK, so the VM is actually running. That's good.

Start the VM from full power off, not save-state. Run until you see the problem happen, then shut down the VM from within the VM OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Please right-click the VM in the main Virtualbox window's VM list, choose Show Log. Save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.

Thanks for the log, we have some good clues:
Host OS:
00:00:01.444017 OS Product: Windows 10
00:00:01.444018 OS Release: 10.0.19043
VirtualBox VM 5.2.22_Sirrix r528 win.amd64 (Nov 12 2018 16:51:33) release log
00:00:28.917435 VMMDev: Guest Additions information report: Version 6.0.0 r127566 '6.0.0'
VirtualBox 5.2.22_Sirrix? What in God's green earth is this? :lol: Never heard of a fork for Windows hosts.

So web-searching tells me that Sirrix distributes a supposedly "secure-er" web browser by distributing it inside a Virtualbox VM with a Linux OS installed.

The problem with this is in the Guest Additions arrangement. The host runs 5.2.22 forked Virtualbox (which we don't technically support btw) and the VM OS has 6.0.0 GAs installed. The newer GAs have services that the older host Virtualbox doesn't have, so the error occurs.

Also, 5.2.22 is rather long in the tooth on a Windows 10 host.

I'd suggest uninstalling the fork of Virtualbox and install from the official Virtualbox http://www.virtualbox.org/wiki/Downloads. Then at least the host version will be later than the GAs version and be able to be backwards-compatible. Also consider upgrading the GAs (or if you really wanted the sandbox-style security, uninstall the existing GAs and have no GAs).

Also, install the official Virtualbox inside the default folder C:\Program Files\Oracle\Virtualbox. There's Windows security protections enabled for that folder that aren't in place for the folder you have the fork in now.
