Here we go...
Recently with the new update of Jupyter Lab when I press the "ctrl+z" command the recovery process applies for all cells I modified before and I want only the cell I selected to be modified. How could I fix that?

Recently I've also experienced the same frustrating problem. I'm adding a picture to illustrate how to disable document-wide undo/redo here.
JupyterLab -> Settings -> Advanced Settings Editor -> Notebook -> Ctrl-F to find "undo" -> check the box "Experimental settings to...".
After that remember to close and re-open JupyterLab
This is due to a document wide history function introduced in JupyterLab 3.2.
You have either to:
1- disable document wide undo redo (in in Advanced Settings Editor → Notebook,)
"experimentalDisableDocumentWideUndoRedo": true,
and reload the page.
Or
2- install a 3.1 jupyterlab with pip install "jupyterlab<=3.1" or if conda conda install -c conda-forge "jupyterlab<=3.1"
