      When launching the game, an error is thrown that states: <some file> failed to download. The file that failed to download is not consistent, and it ranges from missing music files to even missing Java. Here's how to get there: Run Windows + R and type in %AppData%.

       

      I've gathered information about the processes running on about 4 peoples' machines with the error, nothing is glaringly consistent. The location of the users is also not consistent, showing it's likely not an outage in an area. Changing DNS does not fix the issue. Users have this issue whilst not having any AntiVirus or VPN. The ISP is also not the issue as all 4 users have different ISPs.

       

      Downloading an ogg file directly from the servers on a system where the launcher would not work, the download works fine. This is the command I used to download directly:

       

      curl -O https://resources.download.minecraft.net/aa/aa1d3aace1c481ac32d5827fba287294b6bc99fb

       

      Alternate launchers do not work, which is very interesting as the download server is functioning correctly. I personally cannot reproduce this.

       

      Edit 12/16/23:

      Before proceeding with any of the below workarounds, contact Microsoft with your entire error with the link below. This will help them fix the issue on their end.

      If you have an app installed called Killer, get it gone!
      It may come preinstalled if you own a Dell device, which includes Alienware.

      Also, of course, try disabling your antivirus first. If you have one.

       

      Potential Workaround (Windows 10/11): 

      Things to try first:

       

      For Missing Java:

       

      For Missing File:

      This is a little difficult to do, so feel free to ask questions.

      First, we need to get the file on your system. To do this, open Command Prompt.

      To get the URL of the missing file, we need to look at the error generated. After the error says "URL:", copy the entire path. Ex: https://resources.download.minecraft.net/aa/aa1d3aace1c481ac32d5827fba287294b6bc99fb.

      Now, run this command in your Command Prompt replacing "<url>" with the URL you copied above.

      cd Downloads && curl -O <url>

       

      Notice how in that URL it says minecraft.net/xx/ Those two bolded letters or numbers signify the name of the folder this file needs to go in. Run Windows + R and type in %AppData%. Press enter and navigate to the .minecraft folder. Locate the assets/objects folder. In here, create a folder with the same two letters or numbers that your URL says. If it already exists, navigate to it.

      Find your Downloads folder, and drag and drop the file we just downloaded into the folder we just navigated to.

      Wow! You did it! Now, do that for every file it throws an error for. I know, it's painful.

       

      Potential Workaround (Mac OS): 

      Things to try first:

       

      For Missing Java:

      After installing Java, we need to set make Minecraft use it. Click on the Installations tab of the launcher and click Edit Installation next to your version. Click More Options, and click to change the Java Runtime. Once you're in the Finder window it opens, you need to run Cmd + Shift + G. Type into that little box, "~/Library". Locate the Java folder (or Eclipse Temurin), select the version as downloaded above, locate the bin folder, and select the javaw file.

       

      For Missing File:

      This is a little difficult to do, so feel free to ask questions.

      First, we need to get the file on your system. To do this, open Terminal.

      To get the URL of the missing file, we need to look at the error generated. After the error says "URL:", copy the entire path. Ex: https://resources.download.minecraft.net/aa/aa1d3aace1c481ac32d5827fba287294b6bc99fb.

      Now, run this command in your Command Prompt replacing "<url>" with the URL you copied above.

      cd Downloads && curl -O <url>

       

      Notice how in that URL it says minecraft.net/xx/ Those two bolded letters or numbers signify the name of the folder this file needs to go in. Open finder, and run Cmd + Shift + G. Type in that box "~/Library" and click enter. Locate the Application Support folder, and enter it. The .minecraft folder will be found in here, open it. Locate the assets/objects folder. In here, create a folder with the same two letters or numbers that your URL says. If it already exists, navigate to it.

      Find your Downloads folder, and drag and drop the file we just downloaded into the folder we just navigated to.

      Wow! You did it! Now, do that for every file it throws an error for. I know, it's painful.

       

      If you're still stuck...

      There isn't much you can do as of fixing the official launcher. But you're in luck, as there are ways to play the game but using a different launcher. One of these is https://multimc.org, and it has some nice features even the official launcher doesn't.
