TL;DR

The issue can be fixed by updating the cachedGrowthBookFeatures.tengu_max_version_config.external field in ~/.claude.json to "2.1.120" to prevent the local binary symlink from being reset to 2.1.119.

Guidance

• The root cause of the issue is the cachedGrowthBookFeatures.tengu_max_version_config.external field being set to "2.1.119" by the server, causing the local binary symlink to be reset to 2.1.119.
• To fix the issue, update the cachedGrowthBookFeatures.tengu_max_version_config.external field in ~/.claude.json to "2.1.120".
• Verify that the fix worked by running claude -c to resume a previous session and checking that it no longer crashes with the "UKH is not a function" error.
• If the issue persists, try manually updating the local binary symlink to 2.1.120 and verify that it is not being reset by the server.

Example

No code snippet is provided as it is not necessary to resolve the issue.

Notes

The issue is caused by a specific version mismatch and can be resolved by updating the cachedGrowthBookFeatures.tengu_max_version_config.external field. However, it is unclear why the server is setting this field to "2.1.119" and further investigation may be necessary to prevent similar issues in the future.

Recommendation

Apply the workaround by updating the cachedGrowthBookFeatures.tengu_max_version_config.external field in ~/.claude.json to "2.1.120", as this is the most direct way to resolve the issue.
