4.10.1 Crash

Hi, I recently updated my project from 4.7 to 4.10 and now my project crashes…

I have no clue off what might be the problem. It doesn’t happen all the time and when it does, it looks like it’s happening completely randomly. Apparently there are two problem because I get two different crash report.

Sadly I have a limited knowledge of programming so I don’t really know where to start. The project is nearly done and I am a bit freaking out. I have spend the last 8 month working on it and it looks really great (to me at least)…

So if someone could please take a look or tell me where should I start, it would be grately appreciated!

I have included the end of the log. Before that everything looks stable.

Thanks in advance

Hey petitbreton-

Could you post the log files for the crashes as well? Additionally, what were you doing when the crash occurred? Did this happen when you tried to play in the editor or did it crash immediately on opening the project? Is there any code in the project? If so can you compile the code and let me know if there are any compile errors? If you still have a copy of the 4.7 version of the project can you try to upgrade through each engine version (4.7 → 4.8 → 4.9 → 4.10)?


Hey ,

thanks a lot for your fast answer. I moved to 4.10 because there was a bug in 4.7 when I would launch the game that seemed to be fixed by upgrading to 4.10. Then I discovered the nasty crash I wrote this post about.

So I followed your input and went back to 4.7 and fixed the previous bug by the simplest thing… Saving with a new name…

So I am back to a fully functional 4.7 version and will end the project with this version before checking if upgrading to 4.10 is doable.

So problem solved (for now). Thanks a lot for your help. It’s nice to know we are not alone in that infinite ue4 univers :wink:
