[VCPP2017] Runtime crash due to dynamic_cast of m_dynamicsWorld

[lhog]

Hi!

I'm trying to run Microverse and getting runtime crush in attempt to execute
auto softDynamicsWorld = dynamic_cast<btSoftRigidDynamicsWorld *>(m_dynamicsWorld.get()); in ScenePhysics::ScenePhysics() :. Crash message is the following:
Exception thrown at 0x00007FF8448C6727 (vcruntime140d.dll) in Microverse.exe: 0xC0000005: Access violation reading location 0x0000000000000004.

If I replacedynamic_cast with static_cast here and in the body of void ScenePhysics::SetAirDensity(const float &airDensity) I'm able to run the game successfully.

Is this a known issue?

I have no idea why it needs to use a static_cast for m_dynamicsWorld, but is fixed now.
