When I click on build, the editor get stuck on the geometry build, and crashes immediatly.

This was working perfectly fine like 10 minutes ago. Can’t say what changed, I just moved a few lights. Here is the trace.

Actually I can’t even create a new level anymore, everything crashes for no reason at all…

3

The issue can be resolved by removing all temporary folders in the project (Saved, Intermediary, DataCache).

4

Can you specify which folders carry this temp data that can safely be deleted please.

5

Saved, Intermediate, DerivedDataCache

6

I have the same problem
Unfortunately… Deleting those 3 folders didn’t fix the (Build Crash) problem :frowning:

Hi cadviz,

Does this occur in a clean project with no additional content? Are you specifically hitting “build geometry” or are you using the general “build”? Finally, can you post your dxdiag and crash log? The crash log can be found in the filepath \Unreal Projects\PROJECT NAME\saved\logs\

Hi Adams,

Thanks for trying to help…

In fact I did make a question post… and my problem had been fixed by an advice from such a nice guy (like you)… my problem was because of a corrupted light,

Best Regards
