Sensor causes IP connection error

ESPHome
1

Hi, I have configured ESPHome on ESP32 device. I have connected 3 sensors to it. SGP4x, LD2420 and DHT22. I have compiled and uploaded the firmware successfully. Everything works fine when all but DHT22 sensor is connected. After I connect DHT22, the device throws an API error and is unable to connect to Home Assistant

INFO ESPHome 2024.2.2

And which GPIOs did you use?

14 for DHT22
i2c:
sda: 21
scl: 22
scan: true
id: bus_a

uart:
id: ld2420_uart
tx_pin: GPIO17
rx_pin: GPIO16

Do you have esphome updated to the latest?

Post your code and maybe someone can help, everything looks ok to me.
