The problem has been solved. After further checking the documentation, I learned that when using bundletool to generate an APK set archive, a signature file needs to be specified. The reason why I did not specify it before, but the generated apks can still be installed because bundletool will use the debug signature as default, and when I generate this file, the debug signature on my machine is lost for some reason, so the generated file cannot be installed due to the missing signature. After I regenerate the debug signature file on my machine, the apks generated again can be installed. Thanks for the help.
