Hey there everyone! My clan and I have been trying to get into Shadowkeep since about 5pm EST (for reference it is now 10:30pm), and have been inundated with the WEASEL errors. Through various sorts of trial and error, one member found out that leaving the clan supposedly works. I confirmed this, but noticed that when I was invited back, opening my inventory caused me to WEASEL out. I cleared the invite here on Bungie.net, but I realized that the Unicode symbols in our clan tag didnt seem to be translating all that well. We had our clan's owner remove the symbols and voila! Everyone is now able to join and start playing! tl;dr- if you have symbols in your clan's name OR tag, remove them and see if that helps with your weasel errors cheers!
