NCS(nRF Connect SDK) is a good environment to develop nRF52,but it seems not stable until now.
I want to use NCS(nRF Connect SDK) to develop my project ,and met some unknown issuses when start up.
This my local envirment at below:
windows version: win10 64bit
nRF connect version:v3.7.0
Toolchai Manager verison:v0.93
NCS version :V1.60
SES(segger embedded studio) version:v550d_win_x64
nRF-Command-Line-Tools_10_13_0
I follow this guide step by step ,but after all the installations ,I pressed open IDE button ,and enter the SES ,>File->Open nRF connect SDK project . I choose the "blink" project and the "nrf52840_nrf52840" board ,and pressed OK .
This error occurred:

I also chose the other NCS version(v1.5.1,v1.4.2) to install ,the same error .
I also chose the ohter directory to install the NCS, the same error.
I also re-install the SES and nRF connect app, the same error.
I also chose the other PC to test ,the same error...
Please someone help me out...
I just want to start a project via NCS like "hello world".
Thank you.
