In general mypy fails at case sensitivity on Windows (#12880, #18445, both have information for if someone wants to solve this) but since this is a specific case I won't close as duplicate.
(If I had to guess, the import is resolved to an upper case drive letter which passes some case-sensitive filter based on input files)

this causes issues with the mypy vscode plugin which always passes files with a lowercase drive letter. if there are too many errors in other files it won't show any of the errors on the current file

On mypy 1.15.0, I seem to get
bar.py:1: error: Incompatible types in assignment (expression has type "str", variable has type "int") [assignment]no matter which case c has.
