Look at the other log.txt I posted. I did one with plugins, and one without. No change for me. I've tried assigning the throttle to both my Sidewinder and my Thrustmaster TWCS; the problem occured with both. All my other aircraft are functioning normally, and X-Plane sees and recognizes the hardware inputs in the calibration page. As far as I can tell, this is limited to the TBM and the way it's interacting with my hardware.
If you have any further troubleshooting steps you'd like me to try, let me know and I'll share the results!
