Ojs is just loading

Hi
We are facing a problem that the ojs plugin is just loading and we are not able to enter any of those sub-menus in the ojd.
i didn’t do anything but i face this issue. The last action that i had was just unpublished some articles and add their references in the metadata part and published them again.
We are using ojs 3.2.1.2

PHP Version 7.4.15

the Error)logs are:
