  • Is this occurring in every project, or just one project?------(every previous project.)
  • Are you able to reproduce the crash in a clean project?-------(yes,UE4 can startup,but if you create a project with the preset files or a blank,then it’s the load process…and I’m Not yet see the project interface,the Crash Reporter window is pop up.)
  • And I remember when I use the BehaviorTree and double click the service node in the selector that below the root. then Bad things happened.it always Crash and all the previous projects can’t be open,even you create a clean blank one …and it has not finished loading…then crash.
  • I reinstall it about four times and before this I delete the program folder4.12 sometimes …restart the computer several times,but not work…

  • Try updating your graphics card drivers.
  • Does this occur if you attempt to run 4.11.2?

I concur. 4.12.x (currently 5) is crashing like crazy for me. Crashes every time I “save all”. I have to be careful and save objects individually.

Hey Michael,

Please provide your dxdiag. Also, are you able to reproduce this in a clean project? If so, please provide a detailed list of repro steps.

Did you try to update your graphics card drivers, or ensure that you are using the latest?

Hey Sean. Solved the problem after many hours of frustration. Turns out it was a third party (not mine) blueprint that was lingering around in a folder. It came from an example project that had been migrated over several engine versions ago. I wasn’t even using the blueprint in my project but it just being there was causing a crash on save all (even if I hadn’t edited it). Since removing it the engine has been much more stable.
