My project is constantly crashing when the main menu or the game levels are opened. I have just sent the crash report. Can you check it out please? Is the reason going to be fixed in 4.15.1? Thank you.

If you post the logs here, we might be able to help as well.
I don’t see the actual .log file, just the minidump. If you can find your actual .log file (should be in your UE4 directory/Logs I believe), it will likely have an assert near the bottom of the log that tells you why you crashed.
Ok, I have attached the log with zip file to my message above.
Hello tongucci,
The callstack that was submitted was empty, you will need to make sure that your debugging symbols are installed. You can do this through the launcher. I have a few questions for you that will help narrow down what issue it is that you are experiencing.
Quick questions:
Sorry, I didn’t mention that the crash happens on the packaged project. I got the file from C:\Users\Tonguc\AppData\Local(my project folder). If it can be found anywhere else I can look for it?
Sorry, I didn’t mention that the crash happens on the packaged project. Not the editor. Where can I find the log file?
Also this issue does not happen in a clean project. And I have migrated my project from 4.14 to 4.15. Can it be about that?
Hello tongucci,
Could you provide a zipped down copy of your project so that I can take a closer look? If you would like to provide it privately, you could do so by sending it to me in a private message on the forums via a google drive or drop box link.
Thank you, I just sent you a PM.
Hello tongucci,
I noticed that you are using a third party plugin. Could you removed the plugin(s) and let me know if the crash still occurs?
Ok, I’ll try without the plugin and report about the result.
Hi again Rudy, I cannot package the project without that plugin. It gives unknown error. It used to happen the same before creating an empty C++ class. But I doubt the crashes are about the plugin. Because the plugin is not used in main menu level and the game sometimes crashes when opening the main menu level.
Hello tongucci,
Could you provide the logs from your output log when you failed to package (when not using the plugin) so that I could take a closer look?
Ok, here are the logs.

I took a look over the information provided in your logs. I noticed the error: “FAILED: ‘/NeoFur/NeoFur/Assets_Core/Materials/M_NeoFur_Complex’ is not a standard unreal filename or a long path name. Reason: Path does not start with a valid root. Path must begin with: ‘/Engine/’, ‘/Game/’, '/Paper”
I would suggest taking a look at the asset file path for the asset “NeoFur” to insure that the path name is not too long and that it begins with /Engine, /Game, or /Paper. Could you clear this error up and let me know if you are still having issues?
As I checked now, NeoFur is in the plugins folder. I had put it there as said in the plugin’s tutorial. Touched nothing else 
And I didn’t rename anything either. In the editor, everything seems to be in the Content folder. I couldn’t find any issue in the project by myself.
This issue appears to be due to the third party plugin that you are using. We do not provide support for unofficial plugins. I would suggest contacting the creator of the plugin for further assistance.
Make it a great day
