TL;DR

The issue may be resolved by checking for updates or waiting for a fix, as the error code 1W81XU3 is related to a temporary service disruption.

Guidance

  • Verify that the issue persists across multiple restarts and after signing out and back in, as the user has already attempted.
  • Check the existing issues for any updates or fixes related to error code 1W81XU3.
  • Since the web version of Claude.ai works normally, the issue might be specific to the desktop app, and monitoring the app's updates could provide a solution.
  • Consider reaching out to the support team or waiting for a patch, as the error message suggests a temporary service disruption.

Notes

The lack of information about the last working version and additional details limits the ability to provide a more specific fix. The issue seems to be related to the desktop app and not the user's account or subscription, as the web version works normally.

Recommendation

Apply workaround: Wait for an update or a fix from the developers, as the error code suggests a temporary service disruption, and the web version is working normally.
