What was the update that caused the problem?  Microsoft?  HP?

Have you run diagnostics?  Press ESC when booting and run the short diag test.  Run the long one if a problem shows. up.  Do not to restore anything if a memory or disk problem shows up.

This system was shipped with Windows 10 unless I am mistaken.  Did the  update to windows 11 work?   How long was it running windows 11? 

1.  If there are no hardware problems then I recommend you do an install of windows 11 and use the options to save your files.

If you have really serious problems and have lost your files due to disk corruption then a cloud repair may be done.

I am guessing your product ID is 242D3PA#ACJ

please look at the label on your system and verify that ID using the below URL

The cloud recover is below and can be used to reinstall the original operating system

put in your ID.  However, the recover may be windows 10 instead of 11.
