Thing crashed while trying to save. Would've been fine if it just failed to save, but nope, it corrupted the entire file and now I have to do it all over again.

So I had some Fortnite clips in a folder and edited a quick video. The quality was really bad and I was getting frustrated so I ended up just exciting the program. About a hour later I decided to come back and try it again. And.... The videos were gone... I didnt delete them... Checked my recycle bin. Nope gone... Wooooow. Googled it.. Found a post from 2020 on magix website of someone having the exact same issue. Problem is they had like 100's of family videos on a external hard drive and it just delete...

I installed the demo. When adding a video to a project, there is no sound in it. And there are no problems in my PC with sound. Movie Studio 13 or 15 doesn't have these issues. How to solve this problem?
