I just discover that I did not solder the 32.768kHz crystal.
After this external crystal is soldered, it can now work in the debug mode.
May I ask the reason how the crystal resulted in the issue that I encounter?
What can be done to disable the use of the 32.768kHz external crystal?

When the clock crystal is defined to drive the ILO your project will not start when the oscillator "hangs". This will be the case when the crystal is not soldered in.
Go to the low speed clock definitions and remove the WCO. You may alternatively use some APIs to start the WCO and configure it as the source for ILO.
Thank you for your reply.
