Comsol in Ubuntu 18.04 always crashes after clicking Compute button in Study.

The issue happens even with very simple models, for example Heat Transfer by Free Convection. I can open files files, look at the results, but if I choose click Study, then click Compute, Comsol after few seconds crashes with the following error:

A fatal error has been detected by the Java Runtime Environment:

SIGSEGV (0xb) at pc=0x00007f41883939e9, pid=32753, tid=0x00007f40cabef700

JRE version: Java(TM) SE Runtime Environment (8.0_112-b15) (build 1.8.0_112-b15) Java VM: Java HotSpot(TM) 64-Bit Server VM (25.112-b15 mixed mode linux-amd64 compressed oops)

Problematic frame: C [libcsarray.so+0x2f39e9] NodeMaker::reset(bool)+0x89 ...

5.2a also crashes in similar way, but problematic frame is different ("C [libcsxmesh.so+0x5484c4]").

I have NVidia GTX 770, 32 GiB RAM and CPU Intel Xeon X3460.

Did Comsol work for someone in earlier version of Ubuntu? Did anyone was able to run Comsol in Ubuntu 18.04?
