filemtime error?

I installed it, inserted the block, pasted the URL of a YouTube short and it shows me the following error:

Warning: filemtime(): stat failed for /Users/miguel/Local Sites/elamigodelperro/app/public/wp-content/plugins/yt-portrait-video-embed-block/js/video-size-editor.js in /Users/miguel/Local Sites/elamigodelperro/app/public/wp-content/plugins/yt-portrait-video-embed-block/yt-portrait-video-embed-block.php on line 74

am I doing something wrong?

thank you
