Solution
On my computer, the problem is that I had a libassimp.so in /usr/local/lib hiding the system libassimp.so that rviz should actually be using:
Removing it from /usr/local/lib fixed the issue, so now it is loading the right one on runtime and there is no crash when adding RobotModel display (tested with turtlebot3 simulation):
