How to fix Static Driver Verifier results "error"

Question

I am trying to run the Static Driver Verifier on the "Kernel Mode Driver, USB (KMDF)" template project in Visual Studio 2019.

I select the Release configuration for x64 platform. I have only selected the "DriverCreate" rule. If I remove the call to WdfDriverCreate in DriverEntry, then I get "MustFix Defect" as result, with a clickable link that takes me to the report page.

If I leave the code as it is, with the call to WdfDriverCreate then the result is "error", and the result text is not clickable.

I can see that the build and link step is succesful in the UI, and this is also reflected in the file smvbuild.log.

SDV-map.h looks like this:

//Approved=false
//DriverEntry
#define fun_DriverEntry DriverEntry
//TestStaticVerifierEvtDevicePrepareHardware
#define fun_WDF_DEVICE_PREPARE_HARDWARE TestStaticVerifierEvtDevicePrepareHardware
//TestStaticVerifierEvtDeviceAdd
#define fun_WDF_DRIVER_DEVICE_ADD TestStaticVerifierEvtDeviceAdd
//TestStaticVerifierEvtIoDeviceControl
#define fun_WDF_IO_QUEUE_IO_DEVICE_CONTROL TestStaticVerifierEvtIoDeviceControl
//TestStaticVerifierEvtIoStop
#define fun_WDF_IO_QUEUE_IO_STOP TestStaticVerifierEvtIoStop
//TestStaticVerifierEvtDriverContextCleanup
#define fun_WDF_OBJECT_CONTEXT_CLEANUP TestStaticVerifierEvtDriverContextCleanup

sdv\results\drivercreate_SDV.xml contains this:

<?xml version="1.0"?>
<RuleResult xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <defect>false</defect>
  <Name>drivercreate</Name>
  <Result>SDV_TOOLERROR</Result>
  <IsPreCondition>false</IsPreCondition>
  <IsMustFix>true</IsMustFix>
  <isWarning>false</isWarning>
</RuleResult>

SDV_TOOLERROR looks suspicious, but I don't know what the problem is. How can I find more information about what the problem is here?
