Latest version of Flask will not run

Question

flask run ends with the error ImportError: cannot import name '_request_ctx_stack' from 'flask'

Common question it seems, but I cannot find a straight answer for any recent versions of Flask. At present I am using Flask 3.0.3 and I have run pip install -r requirements.txt --upgrade to get the latest version of everything. At present my requirements are

blinker==1.8.2
certifi==2024.7.4
cffi==1.16.0
chardet==3.0.4
click==8.1.7
cryptography==42.0.8
Flask==3.0.3
Flask-Login==0.4.1
idna==2.8
importlib_metadata==8.0.0
itsdangerous==2.2.0
Jinja2==3.1.4
MarkupSafe==2.1.5
oauthlib==3.0.1
pycparser==2.22
pyOpenSSL==24.1.0
python-dotenv==1.0.1
requests==2.21.0
six==1.16.0
urllib3==1.24.3
Werkzeug==3.0.3
zipp==3.19.2

Is there an actual solution to this? Every "solution" I've found comes with other problems and sends me in circles. Is Flask just broken in its current version? And if so, what versions of things can I use to make this work?
