Grayed Out Media/Won’t Connect My Media

I had finished a project, was about to export it, and it said that I was missing media and it would be corrupted or something like that if I exported it with missing media. So, I reconnected all of the media from the files app on my iPad...except one video file which will not reconnect no matter how many times I select the file from my files app. I have searched through the forum, and I've made sure that there is no synchronization errors (which shouldn't have been an issue since I only use Rush in my iPad and Pro on my laptop). I just need extra help because I'm stressed out about it and I'm late getting my video done because of this. Any help is super appreciated!!! Thank you so much!
