Segger Embedded studio conflict NRF9160 and NRF52 DK

Question

Hello

I really need your help !

I am using SEGGER Embedded studio with two EV boards: nRF9160 and NRF52 DK

First I started with NRF9160 with clean installation of the IDE, and a brand new computer, It worked fine

I could build a "hello world" application for nrf9160 and work with that.

Then I closed this environment, and I switched to nRF52 DK, and everything was fine so far.

But when I switched back to NRF9160, I could not open any Zephyr project any more. I kept getting the following error:

I repeated the process again: Format the computer, install NCS/IDE, build for 9160, Switch to NRF52, switch back to nRF9160. And I got the same result.

It seems that after working with NRF52 environment, I cannot get back to NRF9160.

Any workaround?

Thanks
