[Bug] File Write Failure with Absolute Paths in Git Bash on Windows

Bug Description
I am using Claude Code in Git Bash for Windows, and I have recently encountered the error "Error: File has been unexpectedly modified. Read it again before attempting to write it." multiple times when Claude attempts to edit a file. I have determined the error happens when Claude tries to use an absolute path such as "C:/Users/ninte/projects/test/LFMTE_default/style.css" but it works successfully when Claude attempts the same write again using a relative path such as "LFMTE_default/style.css". Please see the current conversation with Claude for a reproduction of the bug.
