APPM and ASCOM camera: Fail to Star Exposure

I did a dec tracking arc run last night via APPM and ASTAP, and it worked flawlessly except for in one camera configuration.  I have an ASCOM camera, Orion 26mp Mono, and if I set the binning to 2x2, and full frame, it fails the exposure with this error: ASCOM CCD Expose Failed(1): StartExposure.
1 2021-08-28 09:34:23.830:       Info,  StartTakeImage, ASCOM Camera: Binning=2, Subframe Type: 0, Duration=3, IsDarkFrame=False
2 2021-08-28 09:34:23.845:       Info,          MsgBox, Message: ASCOM CCD Expose Failed(1): StartExposure
3 2021-08-28 09:34:26.027:       Info,   State Machine, Entering State=WaitPlateSolveNow

If I set the sub frame to 1/2 by 1/2 or 1/4 by 1/4, it works fine.  And if I set the binning to 1x1, it works in all subframe modes
