Have you considered doing a Clean Install of Windows 11? This would give the opportunity to wipe the drive of all partitions to get it cleanest down to the boot level.

The best Clean Install is here:

To create bootable Windows 11 installation media follow the steps under the section to Create Installation media in link Before you Start here: https://www.microsoft.com/en-in/software-downlo...

Power on the PC while pressing the BIOS Boot menu key given here:

Make sure during the booted install to unplug all other drives, boot the media as a UEFI Device, choose Custom Install, delete all partitions down to Unallocated Space to get it cleanest, choose the Unallocated Space, click Next to auto-create and -format the needed partitions and begin install - this makes it foolproof.

After install expedite all Windows Updates including Optional until no more are offered. Then import any drivers from the PC maker's Support Downloads web page for your model that are newer, or branded instead of generic. The most basic thing we need to learn to maintain a PC is how to keep the latest manufacturer's drivers current. Windows drivers are rarely enough.

Make it a diagnostic install by monitoring for the issue after you reinstall each app, Update, settings or any modifications. Have System Restore points set so you can roll back before the change that causes this, if you isolate it.

If you want me to look over your disk configuration to see if I spot anything (about half the time in thousands that I've read) post a screenshot of Disk Management, which I read like a doctor reads X-rays. Follow the steps here so I can see everything needed to advise you: http://answers.microsoft.com/en-us/windows/foru...

Report back results for each step so I know what else to suggest.

Feel free to ask back any questions. Based on the results you post back I may have other suggestions if necessary.
