Home Assistant Tutorial for SEN0691 Causes ESP32 Device to Crash

I'm following the tutorial for integrating the SEN0691 mmWave sensor in Home Assistant. When I put in the configuration from the tutorial, any ESP32 that I use crashes. I'm using version 2026.5.3 of ESPHome and the only sensor connected is the SEN0691. The backtrace is included.

Turns out I had a bad connection. Everything is working correctly now.
