I was using your example of simulator file dht22_test.sim1 and also the given hex file dht22_test.hex to test out the DHT22 Sensor.
At the serial print, it was always showing Failed to read from DHT sensor. I think you can reproduce the problem at your side.
Test on the following parameters:
PC OS Version: Microsoft Windows 10 Pro 10.0.19044 Build 19044
SW Version: SimulIDE-1.0.0-RC2 R1007
Simu File: File Explorer -> Micro -> Arduino_DHT22 -> dht22_test.sim1
Hex File: File Explorer -> Micro -> Arduino_DHT22 -> dht22_test.hex
