Session Start Error: "Communication channel has faulted!"

[terryaulenbach]

Student can't take Moodle quiz in SEB. Consistently gets the message:

SEB failed to start a new session! Please consult the log files for more information.

Student is running Windows 11. and the latest version of SEB. We tried uninstalling SEB and all versions of Visial C++ and reinstalling to no avail.

The reason seems to be that SEB's application components cannot establish a connection to each other:

We had a few reports like these, but could unfortunately up and until today not determine the underlying cause (see #513 and #555). Is your student using any anti-virus or related security software?

This happened to us also, a simple reboot of the computer and closing messaging apps (discord, etc..) has fixed it for us

[dbuechel]

Are there any updates on this? Otherwise, we'd need to close it for now.

I haven't heard back from the student and can't confirm anything so I guess close it.
