Description
I encountered the following problem.
Linux environment
Python 3.11.3
zstandard 0.21.0
>>> import zstandard
>>> hex(zstandard.MAGIC_NUMBER)
'0xfd2fb528'
Win10 environment
Python 3.9.16
zstandard 0.21.0
>>> import zstandard
>>> hex(zstandard.MAGIC_NUMBER)
'-0x2d04ad8'
It seems to be a OS specific difference not related to the Python version. Why is there a difference?

Research direction
Start with the zstandard.MAGIC_NUMBER entry point and reproduce the reported values on Windows and Linux using the stated Python and zstandard versions. Inspect how the constant is defined and exposed, then verify that its value has consistent signedness across platforms; done means the constant reports the expected magic number on both systems.
