Client does not feed to vJoy

[ShinkoNet]

I have a JVS board connected via a RS485 to USB adapter (zk-u485, CH340G chip/driverset).
VJoy is configured for 128 buttons, 8 axis ticked.
Originally it was crashing with errors such as not being able to find vJoyInterface.dll, I was resolving that by adding an existing item (the dll in /lib) to vjoyinjector and copying always to the build dir.
Now, whenever I run the program, I see it lists information about the board, but no events get sent to vJoy when I move the wheel or press any of the buttons on the arcade cabinet.
I've ensured that vJoy is the same version as the SDK version included in this project.

I know that this adapter does work as it can interface with bobbydilley's JVSCore perfectly on a Linux-based system, but I'm looking to use this as I need the Windows platform.

Am I supposed to click "Start listening?" It seems to automatically figure it out on program launch, and when clicking it, I believe it just launches another process that listens it and conflicts over the adapter.

On closer inspection it seems to output this error into the console around the time it connects to the JVS board:
A call to PInvoke function 'vJoyInterfaceWrap!vJoyInterfaceWrap.vJoy::_GetVJDStatus' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
from vJoyFeeder.cs

It seems that the fix for this was PR'd and committed to vJoy here: njz3/vJoy@d56de94
but the latest binary does not have the fix included.
If you want to run this program with vJoy, the DLLs have to be updated to the compiled versions in that repo. Removing the DLL version check in the program and replacing the dlls in /lib with those ones seems to make it work without any errors.
However, the issue still isn't resolved.
I'm getting "Pressed: 0B", "Pressed:0C", etc, in the console now, which means I know it's all reading nice and well, but still, apparently nothing is being fed to vjoy devices 1 or 2. I can see that they are both acquired by the program in the logs too.
I'll see if it's due to the changes in the SDK affecting things or if it might be something else...

I tested with the original version before this commit (fd30735) and it all works fine.
For now, I'll use the program in the state before this commit. Would like to see it fixed eventually, though
