I'm having the same problem on 6.1.30 on Windows 10 Home 64-bit, and can't seem to work around it. I run as a regular user and also have very high security settings, but installing and running as admin doesn't fix it.
How do I get VirtualBox to run? I have attached some log-files if they could be useful in diagnosing.
Virtual Box :Failed to load VMMR0.r0 (VERR_LDR_GENERAL_FAILURE)

6.1.28 had a bug when running on Windows 10 while Hyper-V is enabled. 6.1.30 may still have the bug.
Use 6.1.26 and matching Extension Pack here: https://www.virtualbox.org/wiki/Download_Old_Builds_6_1

On your Windows host, please go to Start > Settings > Update & security > Windows Security > Open Windows Security, select Device security, then Core isolation details. Under Core Isolation, check if Memory integrity is turned on or off. If it's on, turn it off, reboot the Windows host, and check if your issue persists.

The Windows Hypervisor-enforced Code Integrity (HVCI) feature rejects the VirtualBox component VMMR0.r0. A workaround is to disable HVCI aka Memory integrity as follows:
On your Windows host, go to Start > Settings > Update & security > Windows Security > Device security > Core isolation details, turn off Memory integrity and reboot the Windows host.
On your Windows host, go to Start > Settings > Update & security > Windows Security > Device security > Core isolation details, turn off Memory integrity and reboot the Windows host.

Note: I'm finding that this problem appears to be fixed in VirtualBox 6.1.32.
I can now start Virtual Box VMs again with Core Integrity on.
