WordPress 6.8 and Breakdance plugin - 500 error

[apkdesign]

The SpinupWP plugin is giving a 500 error with WordPress 6.8. After downgrading back to WordPress 6.7.2 the Breakdance plugin works correctly again.

Error details:
Breakdance\Lib\Vendor\Whoops\Exception\ErrorException: Function _load_textdomain_just_in_time was called <strong>incorrectly</strong>. Translation loading for the <code>spinupwp</code> domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the <code>init</code> action or later.
