VST3 Windows access bug


I have a problem which I’m trying to solve for days, but without any result. So maybe someone can give me an advice.

The situation is next.
My plugin was tested on many machines with Windows. Everything is working good.
But my friend tested it on his computer and all of his DAWS are crashed. In Studio One log I see a message
“The thread tried to read from or write to a virtual address for which it does not have the appropriate access.”
But this information doesn’t give me a lot. I don’t have an access to his computer.
Again it was tested on many computers with Windows and everything is fine. Only on this machine the same story in every DAW.
