Hey, I’m sorry you are running into these issues.
I’d start by:
- Restart your computer
- Clear the cache on your browser
- Disable any VPN or proxy you may be using
- Try downloading at a different time of the day when the internet traffic is low.
It could have been caused by a number of factors:
- Epic Games server issue: The server may be experiencing high traffic or maintenance, which can cause the download to fail.
- Internet connection: Although you have stated that your internet connection is not an issue, it is always good to check your internet connection, as a slow or unstable connection can cause the download to fail.
- Firewall or antivirus: A firewall or antivirus software can block the download, make sure that the Epic Games Launcher is whitelisted in your firewall and antivirus software.
- Epic Games Launcher: The launcher may be having issues or bugs that are causing the download to fail.
Sorry, I am not sure if Apple Silicon is supported, but if you managed to get the 5.0.3 working; then you should be able to install 5.1 as well.
