open the last toe file, cant find the same one

when I don’t save my project on the desktop and close it, or when i just change the file path , when I open it, there will be not the same project, almost nothing in that. like the picture .there are some waining and when i click the local ,view like the second picture. and now I use 2018.26450 maxOS version.
it’s it a bug ? I need change the version ? or something there i miss


Is the file saved in a path that contains non-ASCII (English) characters? The 2018.20000 series of builds don’t support unicode, the 2018.40000 series fully supports it though so this won’t be an issue for too much longer.

thank you for helping!since now no official version can achieve this , i changed my file name
