whenever I think of studying something bad happens 😭😭

My HP laptop is showing a black screen with only the cursor visible after a recent update. I’ve tried:

Force Restart – No change. Safe Mode – Couldn’t access. Startup Repair – Didn’t work. Uninstall Updates – Stuck on “Choose an account” with no details. I need to back up my photos and access my files. Any advice or solutions to fix this and retrieve my data
