[Bug] Custom Slash Commands Intermittently Not Loading in Powershell

Bug Description
Custom slash commands are intermittently not loading; mostly not loading while using the Claude Code PowerShell version. For example, all of my custom commands in my home directory are able to be used, but none of the project commands. The custom commands had stopped working until I re-ran the claude installer. On the same machine with WSL/Ubuntu, all custom slash commands are available - both personal commands and project commands.
