You need to update your QGIS to at least 3.38 since a new Python version was introduce from that version.

Is the QGIS version change will solve the problems met here ?

The issue is related to the jaydebeapi package which has not been installed. Did you accept the installation of new modules when QGIS was asking ?

I've tried with the version 3.40.15 but it seems to be uncompatible for other reasons. Do you know one version that works in any case?

And yes, I've accepted the installation of new modules but it failed after it

I've accepted the installation of new module

And did you check that the installation succeed ? To check that the jaydebeapi lib was installed, you can try the following in the QGIS Python console (located in the plugin menu):

import jaydebeapi

If it fails you can try the following in the same console:

import pip
pip.main(["install", "jaydebeapi"])
