[Bug] HITL simulation motors not spinning PX4 v1.14.0

hitl bug-report v1.14

### Describe the bug The first problem with hitl was observed in the Airsim sim…ulator when upgraded to the 1.14 version of PX4. Until that with 1.13.3 version Airsim worked just fine ( had a problem with mission uploading, but unrelated to this issue). Then we thought the problem was in the Airsim side, so tried to run the Gazebo hitl simulation, but problem was also present there. As everything connects to each-other without problem, commands also reach and even we can see signal to the motor commands in the logs. But the motors is not spinning. I suspect that the cause might be the dynamic mixer allocation related somehow. ### To Reproduce 1. Upload 1.14.0 version to the flight controller from QGC 2. `git clone --branch release/1.14 https://github.com/PX4/PX4-Autopilot.git --recursive` 3. Follow the [HITL Simulation guide](https://docs.px4.io/v1.14/en/simulation/hitl.html). ### Expected behavior The uav, quadcopter in this case to spin its motors and fly according to the rc input or mission. ### Screenshot / Media ![Screenshot from 2024-01-11 17-03-40](https://github.com/PX4/PX4-Autopilot/assets/63203901/26e7b8cb-55e3-497d-9ace-6b81898b2ef6) ![Screenshot from 2024-01-11 17-04-05](https://github.com/PX4/PX4-Autopilot/assets/63203901/29d775e6-d025-43d7-a34b-5b0373248e37) ### Flight Log From gazebo: https://logs.px4.io/plot_app?log=0fc1709f-9ab5-4cbc-bb72-fb596af114f8 From Airsim: https://logs.px4.io/plot_app?log=11c84cd4-e76a-4c20-81fe-5afaaeee8ce7 ### Software Version v1.14.0 ### Flight controller Cube Orange with ADSB carieer board ### Vehicle type Multicopter ### How are the different components wired up (including port information) Cube Orange plugged into the pc using Serial and other connections are default UDP ports. ### Additional context _No response_
