Hi urosuros1,
I'm Ramesh, here to help you.
The KB5034441 update failing with the error code 0x80070643 is a known issue. You can fix the issue by resizing the Recovery partition to 750 MB or more.
Note: If you don't use Bitlocker, you can simply hide the update using the Microsoft diagcab tool here:

You may use Microsoft's PowerShell script to automatically extend the Recovery partition.
See:

Note: Although the Microsoft script works perfectly and performs proper validations, it's generally a good idea to back up your data before modifying the disk layout.
(or)
To extend the partition manually, please do the following:
- Post a screenshot of the Disk Management window (maximized).
- From an admin Command Prompt, run these commands: reagentc /info dir c:\windows\system32\recovery\ /a diskpart list disk sel disk 0 list part list vol
Post the output or screenshot here.
