[develop-v3] Core panics after connection to AP

Hey,

everything works fine until I connect to my ESP32 via WiFi. After that I keep getting the following error message in an endless loop:

Rebooting...

After I disconnect the core stops to panic but that makes it impossible to upload a config.

I used the current development version of Homie-V3 on a Wemos Lolin32 V1.0.0.

Any ideas what the cause could be?
