OS Build # 19045.3930. Update Troubleshoot tool repair but it does not help. MS Windows Update Catalog does not have the update. Other updates all went through without any trouble. This is a brand new update. Is this a known issue? Is there a resolution specific to this update? (Please do not copy and paste standard procedure)

I had the same issue, i.e. WinRE failed to enable after doing the manual resize due to Bitlocker being enabled. So I followed the WinRE deployment steps from here: Deploy Windows RE | Microsoft Learn (Step1 and used Disk management to assign and delete the drive letter) and after that used reagentc /enable . This was successful and the security update installed successfully afterwards too. ****

all our servers (2022) have this error too (KB5034439) There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80070643)

I don't doubt there's an issue with this update, but all I can say is that one machine where I followed the resize procedure and disabled Bitlocker was able to install the update. I know this is a small sample size but I think there's definitely something about the size of the recovery partition being insufficient. If this is the problem, I'm not really sure how to fix it for machines where the partition layouts are different or where there's some other issue at play. I have another computer where the partition layout parked the recovery partition at the head of the drive so expanding this partition would require a third-party disk manager. We'll see if Microsoft can actually fix this update.

500 devices!? And MS says we should fix it!? Smh if stuff like this happens again I'm gonna start using a mac FFS.

i don't even have a back up partition so this will fail and i have no clue or desire to make one, hopefully they fix it
