Upload file in control app works in development on windows but not in prod on linux

After udating to latest version of scriptcase 9.9.023 I got this error while uploading a file in an field Datatype:Document (Filename )

lang_errm_ivdr: “Could not create directory”;
In the source it refers to not be able to create (nm_mkdir) $dirdoc ‘/_lib/file/doc’

I did not change my production settings in my deploy and to my believe I should not because it worked before.
my settings are
Common Libraries Folder: /_lib/prod
Images Folder: /_lib/file/img
Temp Folder: /_lib/tmp
Documents Folder: /_lib/file/doc

There are no errors in the log on linux (error.log).

Has something changed in the latest version here ?
I know from the past this is really troublesome to solve so I would appreciate some help here.

Working with this version:
PHP: 8.1.6
OS: LINUX PHP-FPM-PROJECT2 5.4.0-91-GENERIC #102~18.04.1-UBUNTU SMP THU NOV 11 14:46:36 UTC 2021 X86_64
ScriptCase Devel: 9.9.023
ScriptCase Prod: 1.0.000
ScriptCase Prod Build: 3

Hello @StephanT

Does this issue still happen in the current version (9.10.011)?

Regards
