Migrated assets to blank project, crashing when adding actors to level

I decided to move my project into a new blank project without the starter content in an attempt to help organize everything. I successfully migrated all of my content into the new project but now I’m having problems with the new project. When I create a new level using the default setting, and I add an actor of any type, the editor crashes with this message:

I drag an actor to the scene and when i release is when the editor crashes, sometimes with a message and sometimes without a message.

Can anyone help me determine what’s gone wrong here?

Hi Skifree,

We could not match this particular crash with our crash reporter data, which may be a glitch on our side if you submitted it, which means I do not have any solid data to go on for this particular crash. However, given that you’ve moved your assets to a blank project, this could be a problem with the DerivedDataCache folder and/or redirectors. If that is the case, you can try to fix this by:

  • Deleting DerivedDataCache folder from the UE4 install directory
  • Selecting the Contents folder in the Content Browser and choosing “Fix up redirectors in folder” & Save all
  • Deleting the Intermediate, Config, and Saved folders

If this does not work, you can send a Dropbox (or similar) link to your zipped project folder to me on our Forums and I’ll see if I can narrow down the cause of the crash.

This can probably be marked as resolved - i haven’t had another instance of this, and have changed everything dramatically since then.

Thanks for the update.
