macOS files automatically lock, preventing changes and saves

MacOS Auto-locking files

Hello, everyone I am seeking help that my Mac Automatically locks all of my files and because of that reason I cant change and save anything.

I have tried some terminal commands like

chflags -R nouchg ~

and

chmod -R u+rw ~

But even that did not work. I did manage to save my documents by creating a new file and copying all the content but it's a workaround I just want my Mac to work.

even doing it the normal way does not work.

Can anyone please help me?

M2 MacBook Air, MacOS Sequoia 15.3.1
