TL;DR

The issue is likely due to a conflict between Claude Code and Windhawk, and adding Claude.exe to Windhawk's process exclusion list may not be sufficient to resolve the issue.

Guidance

• Investigate if there are any other settings or configurations in Windhawk that could be interfering with Claude Code, such as resource limits or priority settings.
• Try running Claude Code with elevated privileges or as an administrator to see if that resolves the issue.
• Check if there are any updates available for Windhawk or Claude Code that may address compatibility issues.
• Consider reaching out to the developers of Windhawk or Claude Code for further assistance, as the issue may be specific to the interaction between these two applications.

Notes

The exact cause of the issue is unclear, and further investigation is needed to determine the root cause. The fact that exiting Windhawk resolves the issue suggests that there is a conflict between the two applications.

Recommendation

Apply workaround: Try running Claude Code with elevated privileges or as an administrator, and investigate other potential settings or configurations in Windhawk that could be causing the issue. This may help to mitigate the problem until a more permanent solution can be found.
