My (simplified) content directory structure:

✔ $ tree content
content
├── index.projects
└── static-git
    ├── files
    │   └── src
    │       ├── Commit.file
    │       └── Common.file
    ├── files.files
    └── static-git.history

3 directories, 5 files

Removing the content/static-git/files.files file makes it compile.
