fatal: unable to checkout working tree
warning: Clone succeeded, but checkout failed.
You can inspect what was checked out with 'git status'
and retry with 'git restore --source=HEAD :/'

Here's how you can try to solve it:

Manual renaming
Go to the repository on your GitHub (or wherever it's hosted), find the offending file and rename it (remove the space in your case).
Then clone the repository again.

Start with the repository entry named .readthedocs.yaml, including its trailing space, and reproduce the clone on Windows. Confirm the filename is corrected and that a fresh clone completes checkout without the reported invalid-path error.
