Sounds like this?

Update sits at the same % for hours
"Working on updates, don't turn off your computer" never finishes
Update fails and rolls back after restart
Settings shows an update error code

Step by step

Wait at least 2 hours. If the drive light still flickers, Windows is working.
If the PC is plugged in and nothing has changed for 3+ hours, hold the power button 10 seconds, wait 30 seconds, and turn it back on. Windows will usually resume or undo the update.
Once you reach the desktop, unplug USB drives, docks, and other non-essential accessories.
Make sure you have free space: Settings › System › Storage. Aim for at least 20 GB free for feature updates.
Check the clock: Settings › Time & language › Date & time › turn on Set time automatically. A wrong clock breaks update downloads.
Run the Windows Update troubleshooter: Settings › System › Troubleshoot › Other troubleshooters › Windows Update › Run (Windows 11 may open the Get Help app).
Restart, then go to Settings › Windows Update › Check for updates and try again.
If one specific update keeps failing, write down its KB number and error code and search it, or bring that info to a technician.

Is it safe to try this myself?

Mostly, if you follow these precautions: Give it real time first: large feature updates can sit on one number for 1-2 hours, especially on hard drives. Never pull power during the 'Working on updates' screen unless it has been frozen with no drive activity for 3+ hours. Back up important files before retrying a failed feature update.
