Guess I spoke too soon 😞
I just updated P3D to v4.3, and immediately started having the same issue again, whereby P3D crashed as it tried to load fsuipc5.dll. I tried installing the latest v5.132c, still no change. I tried completely uninstalling the Saitek drivers and software, and reinstalling first the Saitek drivers and software, but later the new Logitech drivers, and software; and still P3D crashes. I did switch back to the Saitek installs, since the new Logitech seemed to lack a few things (like calibrating the joystick)
I'll attach the fsuipc log, although it looks identical to the last one (except for the first 3 segments of the GUID). The event viewer gives pretty much the same as well (except the hex values)
