Hi , nrf connect V.2.5.0 in windows 10 64bit, fails to launch Bluetooth low energy app. "DEBUG UART read operation on port  aborted" is the log info which i came to know from the log file. May i get any useful info to run nrf connect in windows 10. surprisingly the same nrf connect is working for Programmer (experimental )app. i can connect the BL654 DVK and able to read the memory. I would like to know why the low energy app is not working. am i missing any Dll's to install. attached log file for the same for more detailed info.
