Controller Stick Commands that select a Profile prevents arming

[DLLarson]

Describe the bug
When I try to switch the current PID profile using controller stick commands (https://github.com/emuflight/EmuFlight/blob/master/docs/Controls.md) the flight controller won't arm or respond anymore. Note that trimming the accelerometer using stick commands works fine.

To Reproduce
Briefly test fly with the current default Profile. land, disarm and use the remote controller to select a different profile. In nearly all cases the flight controller stops responding. If I connect to EmuFlight Configurator via USB without disconnecting battery after the "hang" the configurator can't connect. Cycling power on the quad restores communication.

Expected behavior
The selected profile to be selected and arming should be possible. However in most cases the controller with stop responding unless I cycle power on the quad. Sometimes it'll properly select the profile once or twice and then fail. I can't see an obvious pattern.
