When your computer reboots you should be able to use your VPN connections without any connection or performance issues. If that doesn't work I would just uninstall all of the other updates that are listed as the issue might have been injected in one of the other updates as well (it's happened before).

Note: When selecting an update to uninstall, it’s usually best to remove the most recent update first then work your way back until you see the issue you are having solved.

The latest Windows Update is Breaking VPN connections

The recent cumulative update for Windows 10 and 11, KB5036893, has reintroduced one of Windows's most annoying VPN connection bugs. This update issue affects all VPN connections and some users have noticed a significant decrease in both download and upload speeds, while others have encountered difficulties in downloading files from SFTP over L2TP/IPsec VPN. Beyond performance issues, some users are unable to establish VPN connections altogether. Though perhaps unexpected for some, this specific issue has persisted over time, making its recurrence in Windows updates every few months unsurprising. It comes and goes at least once every six months from my experience on both Windows 10 and 11.
