Hello，FluffyPear33825
Welcome to posting in the Microsoft Community.
We very much understand your confusion and inconvenience when you encounter these error codes while updating your system. It may indeed be concerning that a system update could not be successfully installed, but please be assured that these issues are usually resolved in a number of ways and do not have a serious impact on your device.
From the information you have provided, it appears that the cumulative update (KB5053598) is failing to install with two separate error codes: 0x80070002 and 0x80070306. These two errors are usually related to the following reasons:
1. Error code 0x80070002:
This error usually indicates that some files were missing or in an incorrect path during the update process. It is possible that the update file was not downloaded or stored correctly, or that there is a problem with the system's update cache.
2. Error code 0x80070306:
This error is usually related to a system file or service conflict. It is possible that some critical services are not functioning properly, or that there is minor corruption in the system files that prevented the update from completing.
Cumulative system updates usually do not affect the normal use of the existing system, we can try the following steps to narrow down the scope of the problem while trying to fix it, if the problem persists you may need to collect error logs for detailed analysis.
Ⅰ. Disable Security Software Temporarily:
Temporarily uninstall your antivirus or security software to see if they are interfering with the installation process. Remember to re-enable them after testing.
Disclaimer: Temporarily turn off real-time Microsoft Defender antivirus protection in Windows Security. However, keep in mind that if you do so, your device may be vulnerable to threats. So please turn it on immediately once issue fixed.

I have located the link for you directly to the appropriate update package, which can be accessed by clicking directly below.
Once you have downloaded the update package, double-click on it to install it and update your system.
Ⅲ. before re-updating, please reset the update cache file, please follow the steps below:
