Thunderbird won't start anymore.

Hello, I had to uninstall and reinstall Thunderbird on my new Windows 11 computer.
I don't know what happened, but even after several reinstallation attempts, Thunderbird won't restart. It sends a message "The Thunderbird profile cannot be loaded. It may be missing or inaccessible."
Why doesn't it create one during the installation? I cleaned the registry as much as possible and restarted the machine after the uninstallation.
Nothing works, it gives me this message after the reinstallation.
Does this ring a bell for anyone?

Hello
Try the following process:
1) Uninstall Thunderbird through the Windows settings. Keep the data files if prompted.
2) Open Windows Explorer and in the address bar, type %AppData% and press enter.
Locate the Thunderbird folder and rename it; for example, Thunderbirdold.3) Install Thunderbird. (You should have downloaded it from https://www.thunderbird.net/fr/)
4) Go back to File Explorer. In AppData, a new Thunderbird folder should have been recreated.
5) In this folder, click on Profiles then on the folder xxxxxxxx.default. Delete all the contents of this folder, but do not delete the folder itself, which is now empty.
6) In the Thunderbirdold folder you saved, find the analogous folder yyyyyyyyy.default. Copy its contents to the new xxxxxxxx.default folder that you just emptied. (go ahead with a copy/paste).
7) Start Thunderbird.
What we understand well is clearly stated,
And the words to say it come easily.

Hello and thank you for your help.
It does not recreate the Thunderbird folder.

So, I copied my old Thunderbird folder into it that I had copied to my desktop from the old hard drive, which I think I tried yesterday (?). And it works like magic.
Awesome.
I didn't understand anything, but I'm still very happy :-) I've been using it for many years and I can't see myself replacing it with Microsoft's.
Thanks again for your help.
