What's Wrong?

Version: 2.0.14

What Should Happen?

The claude command-line tool is failing on Windows with an ENOENT: no such file or directory error. The tool was functioning correctly until yesterday, but it suddenly started throwing this error today without any noticeable changes to my system configuration or the tool's installation.

The error log shows that the application is attempting to create a directory at the path C:\Users\qlsjt\:USERPROFILE\.config\claude\debug. It appears that the :USERPROFILE token is not being expanded into the correct user home directory path. Instead, it is being treated as a literal string, which results in an invalid directory path on Windows and causes the mkdir operation to fail.

The expected behavior is for the tool to correctly resolve the home directory path and successfully create the required .config/claude/debug directory.
