This appears to be a problem with the binary downloaded from Christoph Gohlke's site (https://www.lfd.uci.edu/~gohlke/pythonlibs/#curses). Note, this is a Windows issue only. To solve, do the following:

poetry add windows-curses
poetry add bpython

then run

bpython-curses

from the terminal. Please close this issue as solved.
