[BUG] Claude misspells username in working directory path, causing permission prompts

What's Wrong?

Same as https://github.com/anthropics/claude-code/issues/17893, which has been closed without a fix.

Claude frequently gets the user folder wrong when reading files. It misspells my user name. That causes permission prompts as it tries to access files outside of the current directory.

For example: I'm in a repository in /Users/harald.koppe/repositories/... and ask claude to analyze something. Then claude tries thinks like Read(/Users/harold.lastname/repositories/... or Bash(find /Users/haar.koppe/repositories/....

What Should Happen?

Claude should read files from the current working directory, not some non-existing made-up directory.

My ~/.claude/CLAUDE.md contains The user is called Harald Koppe. The home folder is /Users/harald.koppe`. Doesn't help. I'd appreciate any other workarounds.
