Access violation reading location in Ext::CpuWorkerThread::execute()

Hello there.
I am current using PhysX version 3.3.4 on my pc.
I seem to be getting some access violation in Ext::CpuWorkerThread::execute().
Visual studio seems to point at…

PhysX3_x64.dll!000007fee3d6adc9()	Unknown
PhysX3_x64.dll!000007fee3d2e88b()	Unknown
PhysX3_x64.dll!000007fee3d30ebf()	Unknown
PhysX3_x64.dll!000007fee3cca732()	Unknown

CatomicEngine.exe!physx::Ext::CpuWorkerThread::execute() Line 80 C++
PhysX3Common_x64.dll!000007fee5818d15() Unknown

Do tell me if I can provide any more details which may help.
I’d appreciate any help! :)
