[Pre-game editor not working error "Unable to find some essential data"]

Sorry for being absent for so long. I don't know if anyone else is still having the same issue but I forgot to mention that I got the game from Epic Games store and I am using Windows  so I'm not sure how to fix this on Gamepass or any other platform. I suppose the fix, in essence, boils down to the "special folders" .xml file that is found in the folder where you pre-game editor is installed. I don't know if SI patched it or not but if they did and if the path in the xml file is correct you need to also make sure that the editor is installed on the same drive where your game is installed.  This worked for me and I haven't had any problems with the editor since. Other than that I really don't have any other ideas or solutions for this other than waiting for SI to fix it through the next patch.

[Pre-game editor not working error "Unable to find some essential data"]

I fixed it. There was a difference regarding the names of the folders where the game and the pre-game editor were installed. One is called "FM24pregameeditor" and the other is "FootballManager24". Those are the default names that the Epic Games installer gives to installation directories so  every time I opened the editor the path in "special folders" .xml file pointed to an "FM24" folder that did not exist. So in notepad I changed the path to "FootballManager24" folder and now everything is working fine.  If anyone is having the same issue just open the "special folders" .xml file in the folder where your pre-game editor is installed via notepad and change the "FM24" path to  "FootballManager24". You can use the "replace" option in the notepad so you don't need to manually replace every word.
