Hey Shera,

Thanks for bringing this to our attention. After looking over your crash report, I can see within the that these are the following errors that are popping up when your project is loading. Also, it looks like you have the Oculus connected to your computer? As the error states, do you have the proper version of Runtime installed on your computer?

Looking forward to hearing back from you, thanks!

Hi ,

Thanks for your fast response. The problem is that I changed those blend space animations names but the editor is still looking for the old names instead of the new ones and that’s why it can’t find it and crash. By the way I changed the names via rename in the editor and saved the project before I close it. And I don’t have Oculus or else devices connected, just my mouse and keyboard.

Important p.s: Instead of crashing when it can’t find an asset or whatever like a dumb app, you can report to the developer team please to add some conditional logic (ex: try … catch) or else in you code to be more wise app and load up normally even if all the assets are not found and just throw the a smart message alerting him with the situation of the lost assets. plus that there’s something wrong with the saving … it’s very buggy separated … like you need to right click and save every single piece of asset to save it all … Save all from the File menu is not working as it should be regarding its name… because I tested that a lot and do save all and multiple saves … but still asking me to save things that i already saved just before it closed if I hit the X close button without making any additional modifications and this is a bug.

Since you’ve renamed your files, you need to go into your project folder and delete the following folders: Intermedia, Saved and Cofig. Once you’ve done that, your project should reopen properly and save the information with the correct file names.

Thanks for letting me know, I knew that there is always a solution because I am an ace coder/programmer before the animation and sculpting new career, just didn’t know the correct setting files to delete to make the app refresh. but as I said before, this is not solid programming, I strongly recommend that you adjust the editor source code in the next version to always use (try … catch) or a similar criteria in all code blocks to notify the with any errors but resumes to open correctly or do whatever instead of crashing. hint: if the project is unusable you can go like that:

Try
     Open "Project...";
     //Project OK!
Catch Error as Ex
     //Project Not OK!
     Message-box("Failed to open project due to " & Ex);
     Shutdown Editor;
End Try
