New Bug Encountered:issue with email report : not sent anymore

[dev2]

Hi all

I am currently in the process of building an email report : it has been working for a while, and suddenly not working anymore.
When it stopped working, I was building the email body (I am pretty sure I did not change any of other settings).

Here are the settings :

Table Name : Employes
Create report : For each row in table
Bypass Security filters : OFF
Condition :
OR( IN([Barcode Employe],ListingMvtsJour[UtilisateurResponsableActuel]),
IN([Barcode Employe],ListingMvtsJour[UtilisateurResponsableInitial]))

and in the “DO THIS” section :
To : [Mail]

This column [Mail] is part of the table “Employe”, and is a column containing exclusively email adresses or blank cells.
“ListingMvtsJour”’ is a slice, and the “View Data” displays only one row, which is what I expect at the moment.

The Workflow report says the email was sent (green binocular), to one user : which is what I expect, one email should be sent to me.
Here is the report :

Many thanks for your help !
