UE4 constantly crashes after download of 4.3 preview

Hello,

my Editor constantly crashes after i just downloaded the 4.3 preview.
Im actually working with 4.2, then i decided to download the 4.3 preview but didn’t run it.
After i open my 4.2 Project the Editor constantly crashes when loading levels or opening/creating Blueprints.
Even deleting all installed Versions did not help.

Hopefully my project is not ruined as i made amazing progress for myself with this amazing engine and don’t want to start from scratch. Thats why i didn’t convert my project to 4.3 yet

I start the Editor with the launcher.

Hi, thanks for the quick response!
i didn’t start 4.3 or convert my project at this point i wrote this.
i only downloaded the preview and my 4.2 engine + project always crashed after that even if i deleted all existing engine versions and reinstall 4.2.

now i found a workaround:

i installed 4.3 again after deleting all engine versions, copied the project, converted to 4.3 that seem to work but forces me to use 4.3 instead of continue my work with 4.2

Yes once you have made your project 4.3 you cannot go back to 4.2 but if you made a copy of your project and you made the copy 4.3, the original project still might be 4.2.

Best Regards!

Hi ,

This sounds like a very strange case to me. I am going to repeat the case as I understand it to make sure that I have it right.

  • You were working on your project in version 4.2.1
  • You downloaded the Preview of 4.3
  • You DID NOT launch the 4.3 version of the editor
  • You opened your 4.2.1 project in the 4.2.1 editor, and you crashed

Question: Did you also crash in 4.2.1 when you load a new project?

THEN (based on your recent response below)

  • You made a copy of your project
  • You updated your project to 4.3
  • You do not experience the crash with the 4.3 project in the 4.3 editor.

Is that all correct?

yes i know, but thats not the problem, sorry to not be clear enough:

since i downloaded and installed 4.3 preview (and after that deinstalling it etc as described)

my editor is actually crashing all the time in all versions and my workaround does not fix it.

the problem is not the conversion of the project both versions (4.2 and 4.3) of the project will cause the editor to crash.
reinstalling the engine does not fix it.

anyways thanks for your help

Hi Stephen,
thanks for looking into this and thanks for your careful reading.
Unfortunately my english is very bad but i will try hard to explain it understandable.

  • You were working on your project in
    version 4.2.1 correct
  • You downloaded the
    Preview of 4.3 correct
  • You DID NOT launch the
    4.3 version of the editor correct
  • You opened your 4.2.1 project in the 4.2.1
    editor, and you crashed correct

Question: Did you also crash in 4.2.1
when you load a new project?
No a new project seem to work properly

THEN (based on your recent response
below)

  • You made a copy of your project correct
  • You updated your project to 4.3 correct
  • You do not experience the crash with the 4.3 project in the 4.3 editor. false - actually the project crashes in all versions but not before i downloaded 4.3

here is the output of the error:

Okay. Thank you for clarifying. So your project is still crashing on 4.3, but new projects work fine.

To be honest, it is very unlikely that the 4.3 download caused this issue, because it is completely different files. I suspect that your project just experienced an issue the last time you saved it, before you downloaded 4.3. But we will keep all options in mind. :slight_smile:

In order for us to get more information about this, please attach your logs in a zip file. You can locate the .LOG and .DMP files in your [project]\Saved\Logs folder.

Thank you.
