I know this seems to been posted for a long time, but this is the first I come to have this issue and have not found any info as of yet. I have recently migrated my project from UE 4.17 to UE 4.18 and now I am having issues with building the project. It seems to take for ever (4 days now progress still at 0.00%) just to Export the Scene (Gray bar part). I do seem to have the following in the Log and I hope it may be of help to any one that may help me to solve this issue.
