Crash after calling control/state over model with OpticalTactilePlugin

[gzfuzz]

Environment

• OS Version: Ubuntu 22.04
• Source or binary build? source build gz-sim version: e237d591d853aad7c95d7f333d65d2412ba4e7f0 built with gcc version: 11.4.0 (Ubuntu 11.4.0-1ubuntu1~22.04) build options: -DCMAKE_BUILD_TYPE=Coverage also reproduced on binary build 8.6.0

Description

• Expected behavior: Gazebo doesn't crash
• Actual behavior: Gazebo crashes

Steps to reproduce

1. gz sim gz-sim/examples/worlds/optical_tactile_sensor_plugin.sdf
2. call /world/optical_tactile_plugin/control/state, with

gz service --timeout 10000 -s /world/optical_tactile_plugin/control/state --reptype gz.msgs.Boolean --reqtype gz.msgs.WorldControlState --req '
world_control {

  pause: true
  step: true
  multi_step: 833568079
  reset {
    all: true
    time_only: true
    model_only: true
  }
}'
