Hi lyx84472636,
I checked the logs. There are many download failures, even when downloading json files at STEP 01. That’s why you cannot open JetPack 4.2, 4.3, or 4.4.
I’m not sure whether this is temporary issue or network unstable. Please check your network, and select the “Download now. Install later.” option to download all components without installation first, then install.
