Hi franck,
To debug, I think you can use something like logic analyzers to get the wave to certify whether it conforms to the one-wire protocol or not which DHT22 uses to work. You can focus on did it produce the start signal correctly.

The DHT22 works fine with Arduino UNO, ESP32, ESP8266… i suspect a Synchro pb.

I use the SimpleDHT libray, i forget to say
