    "Edit With Clipchamp" and Open With Clipchamp no longer properly open the piece of media in Clipchamp

    Hello TreyDavis3,

    Welcome to the Microsoft Community, it's an honour to help you.

    I understand that you are unable to open media files in Clipchamp, based on your description, it seems that you have also tried some options, very much agree with your troubleshooting solution, in order to better help you, I would like to know more about it with you:

    • In order to help you better, I'd like to know more about it. What is the format of the media file you tried to open?
    • Does Clipchamp give you any error messages or prompts when you try to open a file via File Explorer or when you open a media file?
    • Do you have any other video editing software installed that may be affecting file associations?

    Based on your description it seems that you are using the client version of Clipchamp, (if my understanding is wrong, you are welcome to correct me at any time) we suggest that you try to log in with the web version of Clipchamp first to see if you are able to open the files:Quick and easy video editor | Clipchamp

    So that we can troubleshoot if it's an account issue.

    Based on your description, it seems that you have already sought help from Clipchamp, if you haven't tried the Clipchamp support options below, you can also refer to this article to post your feedback to Clipchamp:
