---------------------------
why??

requirements.txt

passlib>=1.7.0 # BSD
bcrypt>=3.1.3 # Apache-2.0

nothing change after OS install just pip install requirements.txt
installed passlib 1.7.4, bcrypt 4.1.3
but failed bootstrap like logs, screenshot

it solved when installed bcrypt 4.0.0

plaese check this
1. additional information bcrypt package 3.x.x > 4.x.x
2. update requirements.text like bcrypt>=3.1.3,<4.0.0

maybe it Good First Issue
