mypy crashes with "Cannot find component" on subsequent runs

Crash Report

Running mypy after the first run sometimes crashes.

rm -rf .mypy_cache fixes the issue, but if I then run mypy a few more times, it crashes again.

Traceback

$ mypy

To Reproduce

This is at work, and it's a rather large repo, so I can't provide easy repro steps. I would be happy to provide additional information that you need.

Your Environment

• Mypy version used: v1.15.0
• Mypy command-line flags:
• Mypy configuration options from mypy.ini (and other config files):

[mypy]
mypy_path = server/python_stubs,server

files = server/,test/

explicit_package_bases = True
enable_incomplete_feature=InlineTypedDict

strict = True
warn_return_any = False
disallow_untyped_calls = False
no_implicit_reexport = False
warn_unreachable = True
plugins = pydantic.mypy

Additionally, we added ignore_missing_imports to most of our libraries.

• Python version used:
• python 3.11.11
• Operating system and version:
• macOS ventura

Bắt đầu với đường dẫn traceback qua mypy/build.py, mypy/fixup.py và mypy/lookup.py, tập trung vào việc xử lý các module mới sau khi .mypy_cache được sử dụng lại. Nếu có thể, hãy tái hiện lỗi qua các lần chạy tiếp theo, sau đó xác minh rằng các lần chạy mypy lặp lại không còn gây ra AssertionError đã báo cáo.
