Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

UMG - Editor crash on opening any widget in 4.10

Opening any widget, even a newly created one results in the engine crashing instantly. The project I've been working on and all the associated widgets do work just fine, I simply can no longer edit them.

This issue affects blank projects as well. The editor has been reinstalled twice.
[EDIT1: The existing widgets work but cannot be edited. Also, no issues in 4.9.2 ]
[EDIT2: Similar issue: https://answers.unrealengine.com/questions/333752/crash-when-opening-blueprint-for-ui.html]

To repro:
1. Create a new blank project in 4.10
2. In the content browser: Add New --> User Interface --> Widget Blueprint
3. Double click the newly created widget to open

Result:
Editor crashes with the following message:
