Issue regarding the Misc Applications module with FreePBX 17

[Monster]

I have a FreePBX 17 machine running on Debian 12 and I’m having an issue regarding the miscapps module.
I’ve installed v17.0.2 of it via the GitHub repository (from the releases page) and I’m getting an error after clicking the add a new misc application button. PHP version is 8.2.7

    <div class="container-fluid">
        <div class="row">

Any idea what can I do to have this working?
Thanks in advance

I just found the “fix” immediately after making this post after struggling with it for a few hours.
For anyone having the same issue: don’t download the one from the tags (releases) page. Get the latest ZIP version from the release/17.0 branch of the GitHub repository which has this issue fixed
