I've found, and I've deleted the file global.py :
same probleme and same output from debug :

I don't find the file metadata.db

In the folder my usual name", there is a file calibre with the text :

Traceback (most recent call last):
File "main.py", line 1185, in initialize_database
File "calibre\library\database.pyo", line 796, in __init__
File "calibre\library\database.pyo", line 47, in _connect
OperationalError: unable to open database file

TypeError: not all arguments converted during string formatting

Hmm do a search on your computer for the files library1.db and metadata.db. If you find any delete them and then when you run calibre choose a different location for your library.

no library1.db and metabase.db in my computer.

So... I'm sure I'll regret calibre but too complicated, too difficult for me +++
thank for yours fast answers
