Big conflict of library versions that can't move user forward after update

Description

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
voila 0.4.0 requires jupyter-client<=7.4.1,>=6.1.3, but you have jupyter-client 8.6.0 which is incompatible.
voila 0.4.0 requires jupyter-server<2.0.0,>=1.18, but you have jupyter-server 2.12.0 which is incompatible.

Reproduce

1. After OS update on hosting sys requires rpds_py-0.13.2-cp311-cp311-freebsd_13_2_RELEASE_amd64 and was error ImportError: Shared object "libffi.so.7" not found, required by "_cffi_backend.cpython-311.so"
2. I decided update virtualenv and update
   pip install --upgrade cython
   pip install --upgrade jupyter
   pip install --upgrade notebook
   pip install --upgrade tornado

Expected behavior

I'm looking some option to update jupyter or other to this version where other instaled libs will be compatible or updated to optmial versions, eg. force re-instal to older main app and related libs. Soo I need some "indication" to right version betwen all version.
Soo.. when update.. then propbably pip should alert and inform possible conflicts and not install new version if older are incompatible in some iteration of update and ask that I'm sure that something can't work or list optimal version to update to minimize impact for some old libs, eg. list of sugested version to update where 75% libs are compatible as tools, etc. or 50%, 25% and of course.. 95% is most of desirable.
Right now I stuck.. fighting with pip to find some optimal version.. but how..

Context

• Operating System and version: LNX freebsd_13_2
• Browser and version:

• Jupyter Notebook version:

- jupyter --version
Selected Jupyter core packages...
IPython          : 8.8.0
ipykernel        : 6.20.1
ipywidgets       : 8.0.4
jupyter_client   : 8.6.0
jupyter_core     : 5.1.3
jupyter_server   : 2.12.0
jupyterlab       : 4.0.9
nbclient         : 0.7.2
nbconvert        : 7.2.7
nbformat         : 5.7.1
notebook         : 7.0.6
qtconsole        : 5.4.0
traitlets        : 5.8.1

From my perspective should exist some tool that will be adequate do build info for:
pip install -r requirements.txt --upgrade
Eg, then tool can build many requirements.txt regarding compatibility range to select, eg.:

1_requirements_25_p.txt 
2_requirements_50_p.txt 
3_requirements_75_p.txt 
4_requirements_80_p.txt 
5_requirements_95_p.txt 

Then user can select 5 as prefix in file 5_requirements_95_p.txt and ok.. not working? Ok.. taking other version of requirements.
I know is big issue and most of out of scope from jupyter, but in fact jupyter is most of advanced env and application where user experiencing problems and doing bad efforts to find solution to repair env and app in case like this ticket.
Soo.. community know many other programmer around python.. let we do something with this regarding this case.
Let we see I'm amateur of python.. what I should do now? How to restore app and in some minimal version jupyter? : )
Not soo easy right? This is big problem..

[ManPython]

In final case I reach some old compatibility around libs manualy... I think as:

IPython          : 8.8.0
ipykernel        : 6.20.1
ipywidgets       : 8.0.4
jupyter_client   : 7.4.1
jupyter_core     : 5.1.3
jupyter_server   : 1.23.5
jupyterlab       : 3.5.2
nbclient         : 0.7.2
nbconvert        : 7.2.7
nbformat         : 5.7.1
notebook         : 6.5.2
qtconsole        : 5.4.0
traitlets        : 5.8.1

From the top message, it looks like this might be caused by voila-gridstack:

voila-gridstack 0.3.1 requires voila<0.5.0,>=0.2.0, but you have voila 0.5.5 which is incompatible.

Maybe a new release of that package will help fix this compatibility issue: voila-dashboards/voila-gridstack#217

I deleted everything.. and installed lower version, then jupyter working but with some difficulties, eg.

1. Notebooks and tree working from last stored password
2. Nothing working in private mode browser where providing this same pass, as 500 : Internal Server Error

• then "libffi.so.7" again.. strange.. coz exist "libffi.so.8" and working..

3. I missing the old style nbextensions manager

[ManPython]

I find problem where something still want "libffi.so.7" again.. strange.. coz exist "libffi.so.8" and working..

From the top message, it looks like this might be caused by voila-gridstack:

voila-gridstack 0.3.1 requires voila<0.5.0,>=0.2.0, but you have voila 0.5.5 which is incompatible.

Maybe a new release of that package will help fix this compatibility issue: voila-dashboards/voila-gridstack#217

I deleted everything.. and installed lower version, then jupyter working but with some difficulties, eg.

1. Notebooks and tree working from last stored password
2. Nothing working in private mode browser where providing this same pass, as 500 : Internal Server Error

• then "libffi.so.7" again.. strange.. coz exist "libffi.so.8" and working..

3. I missing the old style nbextensions manager

[ManPython]

I find problem where something still want "libffi.so.7" again.. strange.. coz exist "libffi.so.8" and working..
Cached or static indication?

You need refresh information here (About Require):
https://jupyterlab.readthedocs.io/en/stable/getting_started/changelog.html#v4-0
As other new version.. coz is not updated.
The problem was solved due relations around _cffi and related argon2
Issue can be closed, but need review docs and indicating the versions problems around whole libs.
What a hell.. around..
