I have a clean P3D v3.4 installed in a new PC. Without FSUIPC4 installed the sim runs good. After installing FSUIPC4 and restarting P3D, seems ok for up to a couple minutes then the sim freezes and Wndows 10 tells me a fatal error has occurred and must close. If I remove the Modules folder the sim again runs fine (after enabling controllers and programming them). I have always used a paid FSUIPC for controls, Warthog and Saitek quadrants, and rudder pedals, with never an issue. I have been able to do some programming without a CTD but not a flight. Please see attachments and I hope I've given you what you need.
Thank you
Jim Tennant
