DHT22 sensor no reading after some hours

After some time of usage the sensor not responding.
But also not showing any error. It stays freeze at the last read temperature value.

Start by reproducing the DHT22 freeze after several hours of use and determine whether readings stop without an error. The issue does not identify a source file, test, or entry point, so inspect the library's sensor-reading path and document a reliable reproduction and fix validation.
