After installing patch for July 9, 2024-KB5039895 Cumulative Update for .NET Framework 3.5 and 4.8.1 for Windows 11, version 22H2 and Windows 11, version 23H2 my GPU is taking a lot of performance hit and some games become unplayable, when starting a game it degrades my PC overall performance,
For example watch a video on Youtube while the game is running becomes impossible, my ethernet speeds drops with 80% on download and 40% on the upload.
After uninstalling this patch all the performance issues are gone.

I would still like to have that patched but also be able to use my PC normally,
Is anyone else having similar issues?
What more information should I report?
How could I report this to Microsoft support?
