I am using DeepAR Studio v 4.4.9 and dowloaded watch try-on tutorial file. But I cannot open the project file from clicking open project button, it show error message as "Failed to open the "WatchTryOnDemo.deeparproj projed. "
Please advise how to fix this problem.

It’s possible some old projects are not possible to open with the new version of the Studio. Could you send the project in question? Also, the watch tryon is no longer available in the DeepAR SDK.
