I am using Unreal Engine 4.2.1 downloaded from the launcher and not modified. Yesterday when I tried to open my project, I was unsuccessful as every time I tried it crashed with the following error message:

`!Id:57b156a88989f91296475cd4b9fd84a1

Unknown exception - code 00000001 (first/second chance not available)

I can still open other projects, but not my own. Please help. I looked at other reported bugs: [Crash] Unknown Exception - First/Second chance - Programming & Scripting - Unreal Engine Forums but in my case it is appearing when I try to open my project, not when I am doing changes to it.

Hi ,

Can you please post your crash logs so we can have a look at what might be occurring? Thank you!

3

Here they are. Hope this helps. link text

Hi ,

Did you make any specific changes to your project before these crashes started occurring?

5

The last time I opened it, I edited some of the settings, such as Maps & Modes, Packaging and General Settings… but I don’t think I made too many changes.

6

Hi ,

Did you add any assets such as new blueprints?

7

No. I didn’t even do any changes to the blueprints last time I opened my project. It was for a really short time, just to see a few settings.

8

What specific settings did you change and what did you change them to? If I know what steps you took I can try to reproduce this on my end.

Hi ,

We have not heard from you in quite some time. I am marking this as answered for tracking purposes. If you are still experiencing this crash, please comment with the requested information. Thank you!

I can’t remember exactly what settings did I change, but I was able to open the project with the new UE 4.3. And there were a few errors in the output log:

Thank you for your support. I will keep my project for a little bit more if you still want to investigate the exception, otherwise I’ll just create a new project and copy parts of the current one over (as I haven’t actually done a lot of work).

Hi ,

I would be happy to have a look if you are comfortable posting the . of your project here.

Hi ,

I was able to open the project on my end. Try moving the folder out of your unreal projects folder, then open it from the desktop. See if it opens there.
