TL;DR

The issue may be related to a configuration or compatibility problem introduced in Claude v1.2581.0.0, and a potential workaround could involve checking the JSON configuration files for any errors or inconsistencies.

Guidance

• Review the HCS Admin log for the recurring Invalid JSON document error (0xC037010D) to identify the specific JSON file or configuration causing the issue.
• Check the main.log file (%APPDATA%\Claude\logs\main.log) for any additional error messages or clues related to the "Session initialization failed: VM service not running" error.
• Verify that the Hyper-V configuration and Azure AD settings are correctly set up and compatible with the updated Claude version.
• Consider reverting to a previous version of Claude or seeking support from the Claude development team to investigate the compatibility issue.
