G431 is relative new, you need new stlink fw and tools to flash. I have similar troubles with first use this nucleo with IDE . Need upgrade stlink GDBserver and fw onboard stlink too.

Thanks for the reply, very appreciated! I am really new to the STM32 family. Could you please be a bit more specific on how to upgrade stlink GDBserver and fw onboard stlink exactly?

Can you connect with STM32CubeProgrammer? Does it show up in device manager?

[CZhen.1]

The STM32CubeProgammer download OK, but still getting the "No ST-LINK detected" problem:

The ST link show up in the device manager OK:

Download install and run STM32CubeProgammer after build in IAR

and try load with STM32CubeProgammer. When you done reconfig IAR to use external cmd flash and try STM32CubeProgammer_CLI

And your IDE screenshot have download success displayed, then your stlink is disconected by code run maybe you use SWD in code , then no debuger will work.
