LPC1769 - "No connection to chip's debug port" by debug!

Software version: MCUXpresso IDE v10.0.2
Sample: NfcrdlibEx1_BasicDiscoveryLoop

Drivers: installed, see picture


Debug Setting:

power: power supply 5v 1000mah

But, if I try to start debug-mode, I get the error-response.

But try a lot of setting and different usb port and jumper-setting, but the error stay the same.

LPC1769 works standalone with "nxp cockpit"

Does someone have an idee?
