Hello Dao Yan
It seems that the Run Configuration of your project is corrupted. The error log shows "Unknown target type". Please open Project Properties, select the "Launch configuration" you are using, and open "Edit Connection" Window. Whether the configurations are correct for your board, including Target type, Memory configuration file, and Initialization file, please see the attached screenshot.

You may create a new project for your board and compare the Run Configurations with your old project.
Best Regards
