Error: jtag status contains invalid mode value - communication failure

This seems ok.
You can also connect pin 1 of STLink 20 pins header to your MCU VDD.
The STLink monitor the VDD and adapt itself.

For the Reset, i don’t know then, maybe try removing the cap and short the resistor.

If you have an oscilloscope, you could check the signal is ok.
