Cannot modify header information – header already sent (CPT related)

Question

Cannot modify header information – headers already sent by (output started at /wp-includes/class-wp-post-type.php:613) in /wp-includes/functions.php on line 6029

This error has seemed to follow me around since WP 5.3 where ‘supports’ needs to be an array. I’ve been able to successfully clear out the error for a small handful of sites by changing the order of the CPT args (throwing ‘supports’ at the end), but on others, the error still persists. I’ve always used an array for ‘supports’, but for some reason, this error is still persisting… Maybe it’s something else in the CPT? I know it’s the CPT for sure because removing the CPT code resolves the error. Can anyone tell me what I’m missing?
