Error: Signal 11 for Coppelia4.0.0 on Ubuntu 18.04

hello, everyone,
I installed the Ubuntu 18.04 version Coppelia on Ubuntu 18.04.
However, when start the program in the terminal "./coppeliaSim.sh". It returned the following error information:
Loading the CoppeliaSim library...
Done!

If CoppeliaSim crashes now, try to install libgl1-mesa-dev on your system:

How to address that?

[coppelia]

Hello,

not sure about the reason why, but the Vortex plugin is the culprit. Removing libsimExtDynamicsVortex.so should solve the problem of the crash (but you won't be able to use the Vortex engine).

Cheers

Thanks for the answer! It works. But I wonder if deactivating vortex engine, what kind of function loss will I experience? Will slow down the simulation speed?

[coppelia]

You simply won't be able to use the Vortex engine for dynamics simulations. You'll have to use the Bullet, ODE or Newton engine instead.

Cheers
