I am currently using version 4.9.2 and whenever i open my player animation bp ue4 crashes, it wont even let me right click the file (in editor) without crashing. This has been occurring for about a day since I conpiled my latest version of my player animation bp. Please someone help, i was not sure what to include (my first time on the ) so ive only included the crash report, tell me if you need anything else.
Thank You :wink:

Hi THEBLACKSOLACE:

It sounds like you have a corrupt asset, in which case there’s not a lot that can be done but to delete the asset and recreate it. However, there are a few things you can try first:

  1. With the editor Closed, delete the Intermediate and Saved folders from the Project folder
  2. Open the project, right-click on your Contents folder in the Content Browser and choose “fix up redirectors in folder”
  3. If it’s still broken, create a copy (Do not overwrite) in the current version of the Engine
  4. If the Animblueprint opens in UE4.13, then you can use this as a reference to rebuild the animBlueprint in UE4.9.2 by having both versions of your project open at the same time

One last note: Be sure to hit send on the when you have a crash so we can compare your crash data with our database. The above crash did not show up in our system.

DO NOT delete the Saved folder as this guy suggests without backup!!!

There is autosave folder under there. I followed what he said and now I cannot go back in version!!!
