I keep trying install this update yet it keeps failing. I already ran troubleshooter said it resolved the issue but the error persists. I also disabled my antivirus and tried again still did not work And I keep getting error (0x80070643) Is this a known issue? All the other updates installed fine without issue.

2024-01-09T21:25:02+00:00 Well it's a known issue on the user end at least and I assume Microsoft is aware at this point. I was just in a chat with support for 2 hours trying to find a fix for this and no dice. They were suggesting using the Media Creation Tool (I didn't do it) but we as users shouldn't have to jump through hoops like this because an update that Microsoft pushed out just straight up won't install correctly.

2024-01-09T22:19:44+00:00 A very large number of users are reporting a failure in downloading this update (KB5034441). There are suggestions to increase the size of the recovery partition to allow the update to succeed. This is a complicated and possibly risky procedure and many are saying it does not work. Microsoft will most likely remove the update or apply a fix.
