What You Asked Claude to Do

Environment:

• OS: Windows 10
• PyCharm: 2025.2.4
• Claude Code: 2.1.114
• Plugin version: latest

Problem:
Username contains a space ("Clemens Li"). When clicking the Claude button,
PowerShell opens and executes:

"C:\Users\Clemens Li\.local\bin\claude.exe"

PowerShell treats this as a string (echoes the path) instead of executing it.
Result: "Cannot launch Claude Code" popup appears.

Related to: #13041 (same root cause, invalid path handling on Windows)

What Claude Actually Did

I don't know. After clocking calude code icon, a claude code powershell ist opened.
After manually CD and execute, claude starts:
