Lost note application ColoNote

Hello,

I am writing to you because I am desperate after losing notes saved in the ColorNote app that contained EVERYTHING I need for work (a list of useful phone numbers, to-do lists, etc.).
I broke my Galaxy S4 mini three days ago, and the screen is cracked and now completely black, but the phone seems to turn on.
I now have a Huawei P20 Lite where I reinstalled ColorNote, and horror of horrors, the restored backup is from 2016!! I don't understand why, as I regularly synced in the ColorNote app, and during my previous phone changes, the restorations worked perfectly...

I have tried A LOT of applications to try to display the interface of my old phone on my PC (a Lenovo) so that I could simply access the notes to copy them, but the free apps do not work or at least, I can't manage it: dr-fone, fonepaw, droid-screen, apower-manager...

I was able to access the data from the old phone, but in the ColorNote folder "backup", I only find files in Word format that are unreadable with Office, and I can't open them with ColorNote on my new phone either...

Do you have ANY solution, PLEASE? (I am willing to pay for a software if I can be sure it works)

Thank you very very much in advance.
