<p>I recently downloaded the latest version of Minecraft to my Windows 10 Computerm and I am having a number of problems with it. <br />I cannot connect to any servers, an the game crashes anytime a world is loaded. This has only happened for single player worlds, as I cannot connect to any multi player worlds.<br />I have tried a number of fixes for this. My computer Mcafee on it and I uninstalled it, and then took all the steps to allow minecraft and java through windows defender. My computer has covenant eyes on it, but this cannot be the problem, because signed into the same Covenant Eyes account with the same settings on other computers, Minecraft works fine. <br />I had attempted to request a refund for my purchase, but Minecraft never responded, so I would at least like to get my account working so I can use it. <br />These are the full game output logs from my most recent attempt at loading/ creating a world:</p>

"java.lang.IllegalStateException: failed to create a child event loop at io.netty.util.concurrent.MultithreadEventExecutorGroup" This line from the report would suggest that there is still an issue being causes by some antivirus or parental control (Covenant-Eyes) software.
