I think you need to rebuild the editor or redownload if you have the binary build

Hello The Dark Enigma -

Just to rule out an issue, I would recommend 's advice, if you are using a source build of the engine, try to recompile it. If you are using a version of the engine from the Launcher then under your library click the down arrow in your Engine version next to Launch and select Verify.

If those do not work can you give me any additional information about the project that is causing this issue for you? Are you getting the crash with a personal project or does it happen with any project including a template project?

Thank You

Eric Ketchum

The engine cannot be started from the launcher, the compiled version works. The compiled one crashes when creating a project.

The reason for the crashes are the special characters in my username (dots and braces). Projects cannot be opened/saved if they are within the directorypath of the username.
