Glad to help. You may be able to bypass the problem by using the 4.6 preview with a copy of your project (don’t convert your current one unless you’re 100% sure there won’t be any conversion problems). The full release of 4.6 will be more stable than the preview, if you would rather wait.
I have a few questions for you that will help narrow down what issue it is that you are experiencing.
Quick questions:
Can you reproduce this issue in a clean project?
If so, could you provide a detailed set of steps to reproduce this issue on our end?
Could you provide more information on exactly when your project crashes (example: on closing the editor, on ending Play in Editor, on exiting stand alone)?
Could you provide the complete call stack from the crash that you are receiving?
We have not heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you are still experiencing the issue you reported, please respond to this message with additional information and we will offer further assistance.
