Log output over JTAG, esp_apptrace_vprintf kills JTAG

[skanky]

I need to use both UARTs for my application on a ESP32S2 so can't use UART0 for the log output.
Working through this page: https://docs.espressif.com/projects/esp ... ic-tracing
I immediately hit a problem. If I include this line in my code:
esp_log_set_vprintf(esp_apptrace_vprintf);
I can no longer debug with JTAG. Instead of F5 starting a new debug session with it breakpointin at the start of main(), instead it doesn't get that far and I get this in the OUTPUT:

I also get a blank VS Code error message inviting me to open launch.json
Can anyone advise what might be going on?

Can anyone from Espressif support answer this please???
