This error message only appears on Windows 7 systems. It works fine on Windows 11 systems. Based on my testing, installing a version higher than 0.20.16 on Windows 7 results in this error, while installing version 0.20.16 works correctly.

这个报错信息只出现在Windows7系统上，在Windows11系统上正常，经过我的测试，在Windows7上安装大于0.20.16的版本就会有这个报错，安装0.20.16版本则正常。

Not sure if it will be any help here but trying to read polars.abi3.so with ctypes.DLL() may yield some extra error information.

(Not sure if the same applies for Windows)

Maybe related to rust-lang/rust#121317

If I understand correctly, rustc no longer generates binaries compatible with Windows 7 by default. So if you build polars from source it may work.
