How to fix:

I found a way in Zhihu.com. It add this: 
import&nbsp;sys
reload(sys)
sys.setdefaultencoding("utf-8")

in "C:\Program Files\LyX 2.3\Python\Lib\subprocess.py". Then the Reconfiguring 
works.


I am not sure someone will read this. If anyone readed this, please reply to 
this mail about the progress. Or I will try other way to feedback this bug.
