It seems that this issue (if I understood it correctly) is fixed in last versions of Lazarus, but several years ago there was an issue with Lazarus unable to save project to non-DOS folder name, e.g. containing spaces or UTF8/WIN12xx characters. Try saving project into folder with only English letters in path (including all the folders in the tree, e.g. C:\Users\用户\桌面\ProjectFolder won't work, try C:\Projects\ProjectFolder).
