DHT11 and LILYGO T3 v1.6.1 does not work?

Hello,
i connected yesterday my LILYGO with the DHT11, as described in the instructions (like: Telemetry | Meshtastic).
After the settings, the symbols on the display were completely messed up and it does not send any temperature or humidity.

Are there currently problems or are the instructions not up to date?
I use the actually image: /v1.2.59.d81c1c0
