To those still experiencing errors; could you check if you have something called cFosSpeed installed on your PC?
This software is often pre-installed on systems with MSI or Gigabyte motherboards, but it is not required for Windows or normal network operation.
We’ve recently identified that this application is causing Error Code: 2011 and Error Code: 2020, and we’re now wondering if it could be contributing to Backend Error also.
cFosSpeed has also been known to cause packet loss and high latency, not only in Darktide but across other applications as well.
