TL;DR

The issue can likely be resolved by checking and updating the browser plugin configuration in openclaw.json to ensure compatibility with the latest OpenClaw version.

Guidance

  • Review the openclaw.json file to verify that the browser configuration is correctly set up for Chrome, as the crash occurs when attempting to open LinkedIn.
  • Check the browser plugin installation by running openclaw plugins list to ensure that the browser plugin is properly installed and enabled.
  • Compare the differences between the linkedin-existing-session.log and linkedin-test.log files to identify any specific error patterns or discrepancies that might indicate the cause of the crash.
  • Consider reinstalling the browser plugin using openclaw plugins install browser to ensure that the latest version is installed and configured correctly.

Notes

The solution may depend on the specific configuration and version of the browser plugin, as well as the OpenClaw version. Further investigation into the log files and configuration settings is necessary to determine the root cause of the issue.
