------------------------------------------------------------------
At first, I cannot reproduce this issue on my Windows 10 notebook where I have
installed multiple applications.
Then, when I prepared a new fresh Windows 10 instance where I have not
installed any software and ran {{pyarrow}} on it, I noticed that I can
reproduce this issue.
After I installed some pip modules and installed utility software, I realized
that this issue does not occur.
Next, I created another Windows 10 instance to investigate what step can avoid
this issue. I checked step by step again. As a result, I found that installing
{{Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019}}
can avoid this issue.
Is this an answer to your question?
