I had managed to complete about 20 pet battles before spontaneously experiencing the disconnects, with no indication of lua errors before or after. I was playing stable for about 24 hours, but after a several pet battles in Dragon’s Blight this afternoon, I began experiencing the same issue. I was able to upload a backed up copy of my Elvui configuration, but I reconfigured all other addons from scratch. I reinstalled WoW and the following addons: I ended up uninstalling WoW entirely and deleting any remaining folders. Just to post and update, I have already tried all of the suggested options. It doesn’t make sense to me why they would suddenly (literally overnight) make the game unplayable. I have spent years creating a layout that I am reasonably happy with, and have had years of stable playtime with it. Has anyone else experienced this? I really don’t want to play without my addons, even if it is stable.

If I rename the WTF, Cache, and Interface folders to force the game into default state, it seems to run stable, but as soon as I get my addons up I start to experience the same constant disconnects every 1-3 minutes. In trying the recommended steps on the help article, I thought I had narrowed it down to an issue with my interface, particularly with Elvui, but after completely uninstalling and deleting my entire WoW folder (including Interface, Cache, and WTF), I am still having the same issue after reinstalling WoW and fresh versions of all my previously non-conflicting addons (namely ELvui, Threat Plates, World Quest Tracker, and Miks Scrolling Combat Text). I have never experienced disconnects this frequent or severe before, and have been trying to see if the issue is on my end. For unknown reasons, I have been getting instantly disconnected every few minutes for the last few days, with the WOW51900319 disconnect error.
