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"

[Closed] Unreal Engine is exiting due to D3D device being lost. (Error: 0x887A0006 - 'HUNG')

I got to correct a mistake for UE4, which I downloaded via the launcher with the help of the program update, which I found on the forum, but what UE4, which I downloaded via GitHub? The program-update not see UE4 from GitHub! Crash occurs when the editor starts.

Here is the error code:
