Either see Redirecting... for using debug_tool = custom and debug_port = localhost:3333 etc for using a pre-opened openocd server, or modify this code locally on your machine

          AlwaysBuild(env.Alias("nobuild", target_firm))

          # update max upload size based on CSV file
          if env.get("PIOMAINPROG"):
              env.AddPreAction(
                  "checkprogsize",

                      lambda source, target, env: _update_max_upload_size(env),
                      "Retrieving maximum program size $SOURCES"))

to say openocd_args = ["-d3"] (or any other debug level. This file should be in <home directory>/.platformio/platforms/esp32/builder/main.py.

Upload and stepping worked fine? Then there’s something with the timing. Running on -d3 adds a considerable amount of debug output and delay between individual executions of commands, which may influence things just in the right direction.
