Ensure content in ajax requests can be json encoded before json encoding.
In version 126.96.36.199 of The Events Calendar, ajax data is not sanitized for non-UTF-8 content prior to json encoding, allowing the request to silently fail.
The list class (the-events-calendar/src/Tribe/Template/List.php) has an apply_filters call, but does not capture the return variable, preventing us from solving this ourselves.
Ensure the content can be jsonencoded:
$response['html'] = mbconvert_encoding($response['html'], 'UTF-8');
Or correct the apply filters call:
$response = applyfilters( 'tribeeventsajaxresponse', $response );
