Have just switched from Movie Edit Pro 2019 to Movie Studio 2022, (win 11) but the problems I had were the same. After 3 days of trying I was unable to successfully burn a DVD with menu. Tried an ISO, tried everything I could think of, such as taking the menus as I found them without trying to move or change anything but the BG. Nope.
Last night I left a DVD mixing down, hoping that in the night it would burn successfully. In the morning I found an error message (for the first time). Looking up this error number I found only one forum entry and that suggested it had to do with the menu structure. Gave it some more thought and recalled that I had used a background in the menu (as well as in the film as title background) from "elsewhere". I had a suspicion . This JPG for the BG was still in the Download folder where it had first landed as I found it in the internet. I had not moved it to somewhere near or in the project folder. I deleted all uses of this JPG in the film and menu - making a new and renamed copy of the JPG in the folder with the project file, deleting the JPG in the download folder, then putting the BG back in the film and menu.
I hope this at least helps someone who might have run into this problem. I would suggest that you study what you did with menu and if you made any changes. The menus seem to be VERY sensitive. There could be other causes as well, but maybe this can help.
