[Bug] File Editing Deadlock: Unable to Write to App.jsx

Bug Description
Claude is stuck reading a file it wants to edit then tries to end but then fails because it thinks it is in use

I have asked Claude to make changes but it turns out that it reads my App.jsx, then it tries to write but then says it's in use. There is nothing open that should have it in use. So i'm tnos ure if it is a tool issues. Very odd so I am going to restart my system and see what hapens.
