I tried the command line to operate VirtualBox and still have the same error message:

Here's the solution:

Modify the following two terms of the registry:
HKEY_CLASSES_ROOT\CLSID\{00020420-0000-0000-C000-000000000046}\InprocServer32 HKEY_CLASSES_ROOT\CLSID\{00020424-0000-0000-C000-000000000046}\InprocServer32

Change their default values to:
C:\Windows\system32\oleaut32.dll

as the picture shows:

At this point, open VirtualBox again and find that it can be started normally.

PS: If you find that you cannot start the virtual machine after opening VirtualBox, you can try to restart the computer.
