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"

UE4 Crash when starting the engine

Hi there. I've been using different versiones of UE4, the last one being 4.16. Recently I installed the 4.21.1 version and was working without problems, but the engine suddenly crashed when trying to save a project. After that point, I was unable to make the engine start again. This is the report:

This started happening also with 4.16, and after that I tried with 4.18, 4.12, 4.14... I uninstalled every engine and even de EpicGames Launcher. Nothing works, I just can't make the engine to start again. I'm working on a Macbook Pro with the following specs:

Model Name: MacBook Pro Model Identifier: MacBookPro13,2 Processor Name: Intel Core i5 Processor Speed: 2,9 GHz Number of Processors: 1 Total Number of Cores: 2 L2 Cache (per Core): 256 KB L3 Cache: 4 MB Memory: 8 GB Boot ROM Version: 250.0.0.0.0 SMC Version (system): 2.37f20 Intel Iris Graphics 550 1536 MB
