TL;DR

The issue is likely related to a compatibility problem introduced in the auto-update, and reverting to the previous version or waiting for a patch might resolve the "Failed to create bridge sockets" error.

Guidance

  • The error message "Failed to create bridge sockets after 5 attempts" suggests a potential issue with socket creation, which could be related to the auto-update changing how the application interacts with the operating system's networking capabilities.
  • Given that this is identified as a regression and it worked in a previous version, comparing the changes between the current version (2.1.111) and the last known working version could provide insights into what might be causing the issue.
  • Since the issue occurs after an auto-update on Windows 11 Home, it might be beneficial to check if other users have experienced similar issues on the same or different operating systems to determine if the problem is specific to Windows 11 or more widespread.
  • The fact that it worked on the first install and broke after the auto-update implies that the update introduced a change that is not compatible with the current environment or setup.

Example

No specific code example can be provided without more details on the application's codebase or the exact changes introduced in the auto-update.

Notes

The solution is speculative due to the lack of detailed technical information about the changes in the auto-update and how the "bridge sockets" are created and managed by the application. Further investigation into the update's changelog or direct inspection of the code changes might be necessary.

Recommendation

Apply workaround: Given the information, the best course of action seems to be waiting for a patch or potentially reverting to a previous version if possible, as the current version introduces a regression that affects the application's functionality.
