MSP-EXP432E401Y: Error -615 when debugging with MSP-EXP432E401Y

Part Number: MSP-EXP432E401Y
Other Parts Discussed in Thread: MSP432E401Y

I am using MSP-EXP432E401Y.
I can no longer connect to the target from CCS while debugging from CCS.
The following message is displayed when downloading the program from CCS.

> Error connecting to the target:
> (Error -615 @ 0x0)

I checked the jumper and connection method, but it seems that there is no problem.
I was debugging by connecting CCS to the factory setting MSP-EXP432E401Y via USB.

PC0 to PC3 are not used in the program being debugged.
