Windows 10: My CPU speed has dropped to 0.80 ghz since installing 2023-09 Cumulative Update for Windows...

On Sept 20, I updated with this at the time latest install. - 2023-09 Cumulative Update for Windows 11 Version 22H2 for x64-based Systems KB5030219 Since the install, my cpu has been stuck at 0.80 ghz where normally it is 2.20. Any suggestions on why this is and what I can do to resolve it? I've since discovered that, after it awakens from hiberation, the CPU is at 2.20ghz for about 90 seconds. Then it drops to 0.79-0.88 and stays in that range. And this is with nothing running or open - no apps, no browsers. Just the operating system and task manager. I have since then on Sep

2023-09 Cumulative Update Preview for .NET Framework 3.5 and 4.8.1 for Windows 11, version 22H2 for x64 (KB5030651) Install

My computer is trying to install 2023-09 Cumulative Update Preview for .NET Framework 3.5 and 4.8.1 for Windows 11, version 22H2 for x64 (KB5030651) but it is stuck at 0% and has been this way for a couple of days. It's preventing other updates from being installed and any updates in Windows Store will not download and install either. I've tried restarting the computer (it's shut down daily) and I've even paused the updates and restarted them. When I did that it redownloaded it and still stalls out at 0% on the install.
