--- Comment #18 from jhu543369@gmail.com --- Starting to think there is a Blizzard problem on the updates. Downloads probably an issue because of global launch of WotLK today, everyone trying to download this and some other content that also dropped. But underneath everything, I noticed that WoW updates fail with a consistent problem:

I have tested this evening these runners: lutris-5.7, lutris-7.2-2, lutris-7.2-fshack, wine-7.17-staging-tkg, wine-5.20, wine-6.23, wine-7.0, Wine-7.2, wine-7.17 (system), wineHQ-7.17 (staging) and lutris-GE-Proton7-29.
Looking at just vanilla 7.17 vs 7.17 Staging, vanilla 7.17 goes into an immediate agent.exe crash loop when the client is launched. With staging, agent.exe launches and it is possible to initiate a new download. What isn't working is updating WoW. I have reported the error to Blizzard as it also happened with WotLK when it 99% downloading.
