    How do I fix Minecraft not launching because the game is already running even though the game isn't running?

    Please follow my recommendations:

    1. Delete the Minecraft launcher that exists on your computer.

    2. Restart your computer.

    3. Install legacy Minecraft launcher for Windows.

    https://aka.ms/minecraftClientWindows

    Once reinstalled, continue with these instructions.

    1. Open Minecraft launcher.

    2. If you are already logged in, click on your image and Gamer tag in the upper left corner of the screen and then on "Logout".

    3. After logging out, delete all accounts registered in the launcher by clicking on the "X" next to each account.

    4. In the Minecraft launcher, enter the Microsoft email and password.

    Regards,

    Alvaro

    Hi nick,

    Thank you for posting in Microsoft Xbox Community. I understand that you're having issues with Minecraft. If it says that the game is already running even if it's not, this means that the game is no longer responding on the background.

    What you can do is to go to task manager, look for Java.exe, right click on it then press "End Task". Once done, try launching Minecraft again.

    If it's still not working, you will have to restart your PC.

    Click the Start button, then click the Power button, and finally select "Restart

    By doing this, the Java processes will be restarted.

    Regards,

    Alvaro

    Hi Frederic Horn





    Greetings!



    Thank you for posting in Microsoft Community.



    Upon reading the description you have posted, it seems that you have an issue with Xbox wherein where you have already tried to launch your Minecraft game but it blocks itself. And just gives you an error code: 0x800705b4.



    Let’s work together in finding the best solution to this issue.



    For me to better understand the issue, I’d like to ask a few questions:

    • When did this issue occurred?

    • Have you already tried to uninstall and reinstall your Minecraft app and checked if it has the same behavior?

    • Have you already tried the troubleshooting steps provided from this support article link from the Minecraft support website: Minecraft Launcher Troubleshooting FAQ | Minecraft Help? (Note: The provided link is a third party webpage. That is why we suggest that you need to vigilant and do not click on any pop-up notifications on their site. In order for you to protect your own data privacy,

    • What other initial troubleshooting steps have you already tried so far?





    In the meantime, we would like you to try the steps provided down below:

    One possible solution to this issue is to try resetting the Minecraft game files. To do this, follow these steps:

    1. Press the Windows key + R to open the Run dialog box.

    2. Type %appdata%\.minecraft and press Enter.

    3. Rename the "saves" folder to "saves_backup".

    4. Restart your computer.

    5. Launch Minecraft and see if the issue has been resolved.

    If the issue still persists, it may be best that you also try uninstalling and reinstalling your Minecraft Launcher.

    Let me know if this helps,



    Sincerely
