gMock Visual Studio test crashes when using EXPECT_CALL - c++

Question

When running my test from the Test Explorer in Visual Studio 2022 [17.2.0], testhost.exe crashes when my unit test has a gMock EXPECT_CALL call in it. What am I doing wrong?
Minimal code:
#include <CppUnitTest.h>
#include <CppUnitTestAssert.h>
#include <gmock/gmock.h>
#include <gtest/gtest.h>
using namespace Microsoft::VisualStudio::CppUnitTestFramework;
using ::testing::Return;
class MockCow
{
public:
MOCK_METHOD0(Moo, int());
};
TEST_CLASS(the_unit_test)
{
TEST_METHOD(the_test_method)
{
MockCow cow;
EXPECT_CALL(cow, Moo())
.WillOnce(Return(42));
cow.Moo();
}
};
If the EXPECT_CALL call is commented out, the unit test will not crash.
I created this project by making an Empty C++ project, then installing the NuGet gMock package, latest stable version 1.11.0, and adding library directories/dependencies in the project settings. The project configuration type is Dynamic Library (.dll).
For C/C++ Additional Include Directories, I have:
$(VCInstallDir)Auxiliary\VS\UnitTest\include;
For Linker Additional Library Directories, I have:
$(VCInstallDir)Auxiliary\VS\UnitTest\lib;
For Linker Input Additional Dependencies, I have:
x64\Microsoft.VisualStudio.TestTools.CppUnitTestFramework.lib
It compiles and links successfully, so the above is just for completeness. I have also tried installing previous versions of the gMock NuGet behavior, but I get the same behavior.

There are other posts about gMock crashes that may be tangentially related, but they either don't have solutions or are missing details and were never updated.

You mix the very different test frameworks.
The more important thing is that you do not initialize Google test framework.
TEST_CLASS, TEST_METHOD are of another test framework, do not perform required pre and post stuff, Google mock is not supposed to work there.
Choose one framework and use it.
#include <gmock/gmock.h>
#include <gtest/gtest.h
using ::testing::Return;
class MockCow
{
public:
MOCK_METHOD0(Moo, int());
};
TEST(the_unit_test, the_test_method) {
MockCow cow;
EXPECT_CALL(cow, Moo())
.WillOnce(Return(42));
cow.Moo();
};
int main(int argc, char *argv[]) {
    ::testing::InitGoogleTest(&argc, argv);
return RUN_ALL_TESTS();
}
