yarl: Trying to build a wheel of YARL with the command `python -m build --wheel` issued at the root returns an error from `_backend.py`

Describe the bug

Using Python 3.9.18

So, if I navigate to the root of the yarl directory and issue the command python -m build --wheel, I get the following:

python -m build --wheel

ERROR Backend subprocess exited when trying to invoke build_wheel**

The same thing happens if I try with building a wheel using frozenlist-1.4.1

To Reproduce

See above

Expected behavior

The wheel is built successfully.
