Some of the error and warning messages in that diagnostics file suggest missing files for portions of the interface - I'm guessing that's what errors like this mean:
No string tables in C:\Program Files (x86)\Steam\steamapps\common\Elemental Fallen Enchantress\Data\English\*.tips
WARNING: SetMultilayerPictureFrame FAILED because mwin with given ID not found - check the tag for this control in DesktopX
WARNING: SetButtonText FAILED because mwin with given ID not found - check the tag for this control in DesktopX
WARNING: CResourceManager::GetEffect could not find file: gfx/fx/fxo/post_camerashake.fxo
CDXSASEngine ERROR: EnableEffect failed to find effect edgedetect
I would try verifying your game cache files because that error and some of the others make me think it didn't install properly. Steam has a built in utility to check for and correct that:
