it's easy if you're on mobile but for pc (im on windows)
you need to download it again, then it opens a folder. click the among us folder, and it's gonna ask you to extract something. press extract or something similar, and it's gonna extract. after that, it brings you to a bunch of things, and one of them is among us. click that and then it should be fine. the only thing i've found out is that it doesn't work from the actual game, you need to launch it from the folder.
