I was encountering the same error while trying to run NuttX 10.x / nimble on NRF52832, tracked it down to insufficient ram available. The nimble nsh-app were present in the builtin-apps internal lists, but when trying to allocate application stack NuttX will return an error code, and it seems all allocation error codes when trying to start an nsh-app will result in that "command not found" error message. I think enabling some memory debugging flags in nuttx will show you the correct error.
So this isn't a nimble problem.
