The solution as you've mentioned and I forgot to applied, was change these compilation flags and distribution options:
Build Settings / deployment / oAlways Embed Swift Libraries = Yes
Build Settings / deployment / strip swift symbol = No
Also when uploading :
unselect 2 first options about BitCode and Strip Swift Symbols

By the way, with the changes, works even with xCode 13.4.1.
Thank you so much

Thank you for the help. We have performed the archive/distribution with xCode 13.4 and 13.2.1, but the same result :-(

Thank you so much for the info, we'll test with xCode 13.4 and post the results.
