'Can't open a project file, keeps showing file existed while it doesn't

There is this flutter project file that I want to import, it's probably an old project, when I try importing it I get this error message of an existing file but, there is none.

I also deleted .idea folder but still showing the same error message "Error adding module to project: Module already exists: aapt". I freshly install android studio on a new PC and still shows the same error.
