Just to let you know, this issue disappears right at the moment as I was finish to switch my PHP version from 7.4 to 8.1. I'm not sure if this was the source of this issue, but maybe this information could help somebody too.

Thanks for all of your great support.

Kind regards

Here is my dev.log file.
I was on dev mode, but I switched to prod mode just now.
This switch doesn't solve the problem.
