Rebooting your PC might be the issue.

Standard deduction when logs dont help:
If your project wont boot, the best option is too manually remove folders labeled
Config > Saved> Intermediate etc in your project directory untill the game boots.

  • Q you need too ask yourself is, “Which files are causing the error?”.*
    Hold shift and place the folders on your desktop, untill the project loads.

If you really know your stuff then you can open the files and find what line of code is the problem.

It may be a plugin, so you would need too do the same with plugins untill you find which one is causing the failure too boot.

Hi. What were you trying to do? Load UE4? Running a specific project? Trying to run the launcher? Please add more specifics. Thanks.
