@jwolffe I managed to fix the “Unavailable Communication Issue between Processes” by disabling line 254-260 in selfdrive/controlsd.py. I got this solution with the hints in

“communication issue between processes” see github issue - https://github.com/commaai/openpilot/issues/2501 disable the issue in controllerd:212 controlsd.py - CARLA

Detailed steps:

1. compile openpilot

git clone --recurse-submodules https://github.com/commaai/openpilot.git
cd openpilot/tools
./ubuntu_setup.sh
cd ..
./update_requirements.sh
USE_FRAME_STREAM=1 scons -j$(nproc)

1. run Carla in Terminal 1
2. run openpilot in Terminal 2

cd openpilot/tools/sim
./launch_openpilot.sh

1. run bridge.py in Terminal 3

cd openpilot/tools/sim
./bridge.py

The fix appears incomplete. Carla video appears in the UI, but hitting the 1 or 2 keys causes “openpilot Unavailable Communication Issue between Processes” message. Openpilot is still not working with Carla.
