Moodle Details:
Moodle 4.3.3 (Build: 20240212)
Adaptable Theme 401.1.10 2022112311
This theme version is for Moodle 4.1. You need to upgrade Adaptable to a version that supports Moodle 4.3, currently 403.1.4 2023111805.
I don't know for certain this is causing this issue but it's a likely candidate.
