Good morning,
the server is provided by Cloudways, on the top of DigitalOcean, so I suppose it is a Linux/Ubuntu, PHP 8.2, MariaDB 10.6
My PC is Win 10, Chrome Version 120.0.6099.200 (Official Build) (64-bit)
It fails even using yoiut CSV demo: https://www.webtoffee.com/wp-content/uploads/2020/10/Sample_Users.csv
Last successful import was on 2023-07-28 07:38:28
I do not remember the package version at that date, but I always keep the latest version.
Thanks a lot for your help
