mitmproxy fails to start because of indygreg/python-zstandard#238 , no idea yet about other failures.

Pickle exception failures are something about the changes in python/cpython#122214 intentional changes of python/cpython#122771, we need to adjust the expectations.

The asyncio loop failure in tests/CrawlerProcess/asyncio_enabled_reactor.py is documented and handled in scrapy.utils.reactor.set_asyncio_event_loop() so the failing code may need to be modified in a similar way (or even call that function, depending on the intention of the reactor installation code in the script).

uvloop failures are MagicStack/uvloop#637.

Not sure if there is some problem with pytest-cov ("Exception: ConfigError("Couldn't read '/home/runner/work/scrapy/scrapy/:' as a config file")"), note that we pin an older version of it.

Looks like there are no new warnings.

After looking at the OS X job I see that, surprisingly, #5306 reappeared. I wonder if it's some kind of an lxml issue.

There is also an OS X-only deprecation warning in twisted.internet.process._BaseProcess._fork() about forks in multi-threaded processes, but it turns out to be 3.12+, not 3.14+, see the note in https://docs.python.org/3.13/library/os.html#os.fork. Not sure if it's possible to address it and also not sure if it's specific to scrapy.utils.testproc.ProcessTest or happens in normal Scrapy usage too.

This is now additionally blocked on twisted/twisted#12426 (before switching to pytest-twisted the loop was created when install_reactor() was called in conftest.py)
