What's Wrong?

For the last 24 hours I have been getting this error on existing coworkers sessions. 'This task didn't load properly
RPC error: ensure user: user confident-fervent-rubin should already exist but does not, and recovery failed: home directory /sessions/confident-fervent-rubin does not exist: stat /sessions/confident-fervent-rubin: no such file or directory' - I have restarted the Mac, I have deleted cache files, I have deleted and re-installed Claude desktop

What Should Happen?

It should accept a new prompt without error
