hi, i am a student, i am new to nrf52840 DK. I downloaded Gooligmelec "nrf52test-led-battery" from github and open Solution inside SES . it was running ok. when suddenly. it shows "can't load project file "C:/Googlimumelec/nrf52test-led-battery/project/led_battery_pca10056_s140.emProject" is invalid. The reported error is "tagName mismatch". It does not allow me to re-open Solution or open Studio folder as it keeps giving the same error as shown below.
I have not even edit anything. i was just trying to learn from the example in Gooligmelec's github. appreciate your kind help. Thank you
