Crash Upon Loading Minecraft World (java.lang.IllegalStateException; failed to create child event loop)

Previously, I have been able to run Minecraft on my computer without issue. However, after a long break since my last time playing, I am having difficulty loading any minecraft world on both singleplayer and multiplayer. I have tried just about everything between uninstalling and reinstalling Java and Minecraft, updating drivers, and exhausting all possible resources on this issue. I do not run any antivirus software such as Avast or McAfee that might prevent it from running, which seems to be the most common reason for this issue. I'm really looking for someone to point me in the right direction because I'm not sure what is causing the issue. I attached a sample crash report. (This issue has been solved, I added a forced IPv4 into the JVM Arguments in the Launcher)
