I also uploaded the log file to ChatGPT and this was the response:
The log file primarily consists of SELinux audit denials indicating that Android Auto (com.google.android.projection.gearhead) is repeatedly being denied access to various system files and properties. These denials are due to SELinux policies enforcing strict access controls, which are designed to isolate applications from certain sensitive parts of the Android system for security reasons.
The specific denials include attempts to read system properties and files, such as build attestation properties, userdebug, or engineering properties, and attempts to lock certain system framework files. These actions are being blocked by SELinux, which is operating in enforcing mode (permissive=0), indicating that these operations are not allowed under the current security policy.
Towards the end of the log, there are indications of session expirations and disconnection events related to the Android Auto application, suggesting some operational issues possibly related to or resulting from the earlier denied access attempts. The disconnection and session expiration messages might be symptomatic of broader connectivity or compatibility issues between the Android Auto app and the vehicle's system.
Understanding and resolving these issues may require a combination of updating Android Auto, checking for compatibility issues with the device's operating system, and possibly consulting with device or vehicle manufacturers for updates or patches that address these security and connectivity concerns.
