Hi @CooperGroove2015,
Thanks for reaching out! We're sorry to hear about this. Could you please let us know if the video has any clips or assets used from your local device or from Adobe stock? Are you getting any error messages?
Did you try using the other suggested browsers (Safari, Microsoft Edge, and Google Chrome) or incognito mode to see if it makes a difference?
Also, try clearing the browser's cache and cookies, and restarting the browser and try again. For more information on how to clear cache and cookies check this link- https://adobe.ly/4a5ipUF and how to use incognito mode- https://adobe.ly/4a2UzZV
