Hi You can try to unlock the device to make it with factory default values.

Details to do it you can refer to the user's guide 3.3.4.3

And here is a E2E thread that may help you https://e2e.ti.com/support/tools/code-composer-studio-group/ccs/f/code-composer-studio-forum/1008038/uniflash-unlock-msp432e41y-from-gui

Hi,

Could your .hex file application be changing the setup of the JTAG pins.
This is surprisingly easy to get wrong - I've done it and seen at least one other forum post where someone else has done it. My application was using the pinout.c file generated by an older obsolete tool and it reconfigured the JTAG pins as GPIO. After that, the debugger would not connect.
If so, you will need to perform a factory reset to get the chip back.
