Windows 10 x64 directinput8 related device compatibility issue

Hello,

I'm trying to troubleshoot a error/crash effecting my system under Windows 10 x64. Reviewing crash dumps and event viewer points towards the use of directinput8 (specifically dinput8.dll called by the Immersion Direct Input Effect dll) in order to call force feedback effects under multiple applications. From what i gather this issue appears to effect a number of older devices by a number of manufacturers. This problem did not present in Windows 7 x64.

I did come across this information: https://cookieplmonster.github.io/2019/08/02/win10-dinput8-crash/ indicating a bug exists with dinput8.dll I grabbed my Windows 7 x64 dinput8.dll and ported it to Windows 10 x64 but nothing changes.

I note that 32bit programs which utilise the 32-bit dlls under Windows 10x64 work fine, as does both the 32 and 64 bit sample programs FFconst.exe bundled with the DirectX SDK. So the driver/device does work under Windows 10 x64. This video further confirms that the driver works/worked with Win 10x64 as of version 1709 https://www.youtube.com/watch?v=cxeaGz3s5aM

So it looks like something has changed in Windows 10 x64 that has broken software compatibility with a number of programs utilising directinput8. This thread https://gamedev.stackexchange.com/questions/68757/is-idirectinput8finddevice-totally-broken-on-windows-7 indicates that there have not been changes to dinput8.

Grateful for any assistance to understand what is going on here.
