You mention in your opening statement that you were seeing an "EXEC format error." Can you elaborate on this? None of your included log information depicts this error message so I'm curious.

The reason I'm curious is because that error typically occurs when Linux attempts to execute a binary compiled for another CPU Architecture. I'm doubly curious because you're working with automotive software which makes me think you're attempting to run software compiled for the x86_64 architecture on arm64 architecture like a Raspberry Pi. I suspect this is your issue. This happens pretty often. Here are some similar threads for people experiencing similar issues.

You can find many more if you search google.
