Bravo Throttle Quadrant (BTQ)- Works only in XPLANE

For the past two years, I have had no problems using Honeycomb's BTQ in P3D V4/V5, MSFS2020 and XPlane 11.  Yesterday, I attempted a flight in MSFS2020. After it loaded, I noticed that the throttles were fluttering approximately mid-way through their axes in the simulator. I attempted to move the throttles using the BTQ and while they did move in the simulator, it wasn't through their full range nor could I get the throttles to move to their close position and stay there.  I attempted closing down the sim and computer, then restarting and reloading a flight.  The same problem occurred,

I tried loading flights in both P3D and Xplane to see if the problem was isolated to MSFS.   The same problem occurred in P3D but in XPlane the throttle were in their closed position when the flight loaded and movement was fine.An

I also tried: a) detaching and attaching the BTQ to my system.  b) calibrating the axis in using first the windows game controller setup and then calibrating the axis in both P3D and MSFS; c) loading different aircraft in both P3D and MSFS - again, no change.   Any suggestions before I try uninstalling and reinstalling MFS2020?
