CARLA Simulator Launch Error with NVIDIA RTX 3080 on Ubuntu 20.04 - Seeking Assistance

---

CARLA version: 0.9.13 RSS

---

Platform/OS: Ubuntu 20.04 (No VM, Dual Booted, Direct GPU Access)

---

Problem you have experienced: Upon attempting to launch the CARLA simulator on my system, the application crashes with an error related to BadMatch (invalid parameter attributes), mutex lock failures, and a segmentation fault. This issue prevents the simulator from starting.

---

What you expected to happen: I expected the CARLA simulator to launch successfully without any errors, allowing me to simulate and test autonomous driving scenarios.

---

Steps to reproduce:

1. Ensure that NVIDIA graphics drivers and OpenGL are correctly installed and up to date.
2. Navigate to the CARLA directory.
3. Execute ./CarlaUE4.sh to launch the simulator.
4. Observe the terminal output, which includes a BadMatch error, mutex lock failure, and eventually a segmentation fault, leading to the application crashing.

  • Graphics Card: NVIDIA GeForce RTX 3080
  • Driver Version: NVIDIA 535.161.07
  • CUDA Version: 12.2

• I've confirmed that my system's OpenGL version and NVIDIA drivers are up to date.

• The issue persists even after ensuring there are no known compatibility issues between my hardware and the CARLA simulator.

• I am running Ubuntu 20.04 on a dual-boot system with direct access to the GPU.

• Before posting, I have searched among existing issues and discussions on the CARLA GitHub and CARLA forum, and consulted the documentation and FAQ at http://carla.readthedocs.io, but nothing is working

I appreciate any guidance or solutions to resolve this issue and successfully launch CARLA on my system. Thank you!
