Welcome caillouvic,
[To do when you're not playing]
Apparently you've never:
Make a backup in Xeester (Start > Backups management... > Backup DESKTOP-XXXXXXX...)
Which would have made it possible to restart from this point of safeguard to solve your problem quickly.
Try this :
Make a backup in Xeester (Start > Backups management... > Backup DESKTOP-XXXXXXX...)
Then, once the backup is completed,
Check the list of sessions to see if the last parts show "0 hands" and delete them:
(see example)
Once finished :
Repair the database in Xeester (Start > Repair the database)
And to finish :
Import> Import old untreated files ...
If after that the problem is fixed, make a new backup:
Make a backup in Xeester (Start > Backups management... > Backup DESKTOP-XXXXXXX...)
