how to reset and go back to captive portal?

[wjquigs11]

Is there a way to reliably reset the wifi configuration so that the MCU goes back into captive portal?
I have tried both NW.erase() and NW.reset() (followed by a 1-second delay and ESP.restart() but when I try to reset this way I consistently get an error
E (1516) wifi_init_default: netstack cb reg failed with 12308

However, I don't know if this is a problem with NetWizard, or a problem with the ESP32 TCP library code, because if I enable debugging with these flags, the issue goes away:
-D CORE_DEBUG_LEVEL=5
-D CONFIG_ESP_WIFI_LOG_LEVEL=5
-D CONFIG_ESP_WIFI_DEBUG_PRINT=1
-D ARDUHAL_LOG_LEVEL=5
-D CONFIG_ARDUHAL_LOG_COLORS=1
-D ESP_PLATFORM=1
-D ARDUINO_ESP32_DEV=1
-D DEBUG_ESP_WIFI=1
-D DEBUG_ESP_PORT=Serial
Setting log level = 3 or 4 also causes the issue, so it's quite timing-dependent. Whatever the additional logging is doing is causing enough delay to mask the problem.
Also, it occurs whether or not ASYNC TCP is enabled.

I've attached my platformio.ini (as .txt) for reference.
