Purge of old backup doesn't work anymore since bump to 15.10

Hello there,

Since upgrade of hosted gitlab fro 15.7 to latest 15.10, the purge of old backup doesn’t work anymore.
Did someone experienced such a problem ?
Thank you

Here is the list of files at the beginning :

[root@srv-prd-cicd001 docker-git-backup]# ls -la
total 67991788
drwx------   2 chrony root          116 30 mars  10:56 .
dr-xr-xr-x. 23 root   root         4096 29 mars  21:59 ..
-rw-------   1 chrony input 34811566080  1 janv.  2012 1680162730_2023_03_30_15.10.0_gitlab_backup.tar
[root@srv-prd-cicd001 docker-git-backup]#

And the execution log of the backup :
