You should probably include a screen shot of the message log in order to get any kind of help. Just putting a screen shot of the popup message for the error, gives to little information for anyone to help you.
There is nothing on the error code some assets i can not open it. And i have Generate the project file and I even try the custom build from github nothing works
There is nothing in the message log? In the screen shot you have provided, there is no tab that I can see that shows you have the message log open. The way to open the Message log is to, click on Windows on the toolbar at the top, hover the mouse over where it says Developer Tools, then click on Message Log.
you need to determine first if those assets, that the message log is saying, that it cannot find, if they exist, by checking to see if the content browser can see them, and that they are in the correct directories. If the content browser cannot see them, this would indicate, that the assets should be re-imported, or re-migrated into the project.
if i re importet them the editor will be crash.but i found the problem.that problem its i wrote Special german Spells in the editor and they can not read in this version how can ni change they name of the refrence in the visual Studios ?
i fix it now i downgrade the project and rename the Asset in the content browser.all german special Spells much go away
