Sidewalk failed at initializing stage

Hi,
We have build our own sidewalk device that use Raytac MDBT50Q module ( nrf52840) and lora module.
1/ It works well with LoraWAN example ( this meant spi interface is worked)
2/ But when running sidewalk example ("sensor monitor demo", it sometimes work, sometimes got this error ( at the state of initializing) "Failed to initialize sidewalk err:-1"
Below are screenshots for work and error console log

We tested with some different lora sx1262 modules, include Lora Shield module, but it has the same issue.
Any guidelines for situations will much be appreciated. 
Thank you
