Crash in building lighting

Whenever I try to build my lighting it always result in crashing of the Unreal Engine.

I have Ubuntu 18.04
Intel i3: 3.9 Ghz
8 GB ram
GTX 750 Ti 2GB

Here’s my crash logs:

Any help is appreciated.
Thanks :slight_smile:

Most likely your PC specs are too low

But I have Windows 10 before with same PC specifications, I did not encounter any issues like this.

Is this may caused by something else?
