I keep getting msg”: “‘dict object’ has no attribute ‘item'”

i want to check if files is existing using with_items
and when those file exist, I want to modify some part of the file using lineinfile module

what is the best way to do this?

below is the code i tried but I keep getting an error msg”: “‘dict object’ has no attribute ‘item'”

    - name: check for existing files
      stat:
        path: "path/{{item}}"
      with_items:
        - file1
        - file2
        - file3
        - file4
        - file5
         register: file
        
    - name: Update file
      lineinfile: 
        path: "path/{{item}}"
        regexp: "^PASSWORD=" 
        line: "PASSWORD=password}"
        backrefs: yes
      with_items: "{{file.item}}"
      when: "{{file.stat == exist}}"
