The author demonstrates the process on 1.18 RC1 by unplugging and re-plugging, pausing during the parameter load phase, and notes it eventually fails without loading parameters, a behavior also seen on daily and stable. They emphasize it appears only with the 1.18 release candidate firmware and not with Viewground control. To confirm the PX4-related problem, they switch to Configure Firmware and show that upgrading to 1.17 works correctly with parameters loading quickly.
