Not unlocking submitted portfolio after evalution

I'm trying to use Mahara, it's the first time I try to install it and I'm in trouble with something.
Before explaining my problem let me say that I've installed Mahara from it git repository and I use 22.10_STABLE version on a Ubuntu 20.04, php 7.4 and mysql Ver 15.1 Distrib 10.5.9-MariaDB.
The installation was great and I can use Mahara, but when I try to create my first collection and my first page and submited it to a group (created before).
When someone try to unlock it I've got an error in my logs (and in the web browser, but less verbose and disapear in 5 seconds), and it stay blocked on 'Unlocking..'.

I've got the stack trace but i can't post it because I'm a recent account...

See the main message in it :

[WAR] d9 (lib/errors.php:852) Failed to get a recordset: mysqli error: [1064: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '?  LIMIT 1' at line 1] in EXECUTE("SELECT * FROM "lti_assessment"  WHERE "group" = ?  LIMIT 1")Command was: SELECT * FROM "lti_assessment"  WHERE "group" = ? 

The error is about a simple SQL statement who was not correctly syntaxed, and it's about the table 'lti_assessement', my installation is fresh and I doesn't use some LTI in it.
Thanks for your help

Hi Tristan,

I'm not able to find the issue from what you have posted - are you able to post more of the error backtrace so I can see what functions were called before the call to the SQL itself. These should be the lines below (called before) the ones that contain 'htdocs/lib/dml.php'

Hi Robert,

Were you able to reproduce the issue raised ?
For my part, I reinstalled Mahara locally on Xampp, and I'm facing the same problem (same error).

For those who have the same problem, I resolved my issue : 

It seem's to be a problem who come's with php 7.4 (I don't know why)

Downgrading to php 7.3 resolve the issue, it work well now.
