w1r3 I found a solution but this only works with Android devices.
-Open the ASIAIR app and install the old version.
-Then you reset the ASIAIR and switch it off.
-Then delete the app and go to the Play Store and deactivate automatic updates.
-Open this page and download this file and install it. https://apkpure.com/de/asiair/com.zwoasi.asiair/download/2.1
-It must be version 2.1-10.74 (Mar 3, 2023)
-If you haven't set up your Sony A74 then this video here will help you. https://youtu.be/5KsZ-79CsxA?si=iOp3ny7tVtD4GE4m
-You also need a SNAP cable for your camera and ASIAIR.
-Once you have everything connected, turn on your ASIAIR and leave the camera off.
-When the beep came, connect your Android device to the ASI Air and then turn on your camera.
-If the Sony A74 has connection problems, simply turn the camera off and then turn it back on.
I was able to connect my A74 and can use everything without any problems.
I hope I was able to help you and wish you clear nights.
