open_database error

When trying to open a database i get the error:
SQLiteException: code = Error (1), message = System.Data.SQLite.SQLiteException (0x800007BF): SQL logic error
Det angivne modul blev ikke fundet.
ved DHI.Amelia.DataModule.Services.DataSource.DataSourceSpatiaLite.OpenDatabaseCore()
ved DHI.Amelia.DataModule.Services.DataSource.BaseDataSource.OpenDatabase()

the code look like this:
from mikeplus import DataTableAccess
from pathlib import Path

sti_db = Path('C:\Users\......\Test.sqlite')
db = DataTableAccess(sti_db)

db_open = db.open_database()

The database has been made in a 2024 version of the mike+ program.
