I have a very small scene:
Short Hallway
Chair
Side Table
Couple of lightballs
Rect Lights

When I bake the scene in 4.20.1 I had no problems. But now after updating to 4.20.2 UE4 keeps crashing when I press build. More specifically it keeps crashing at the starting up of Swarm connection…

Also I get this error “Qt5Multimedia.dll was not found”, “Qt5MultiGui.dll was not found”, “Qt5MultiCore.dll was not found”, “Qt5MultiNetwork.dll was not found”,

Verified my UE4 version, the seemed to fix it. I can now bake lights no problem.
