Matrix: Element Desktop is unusable on Windows [UPDATE]

Currently, some users are seeing the following error message in Element Desktop for Windows:

Event indexer threw an unexpected error

Error: internal error in Neon module: called `Result:unwrap()` on an `Err` value: SendError { .. }`

There is currently no reliable solution to fix this problem. A clean install might help.

Workaround

[UPDATE]

These notifications can be avoided by turning off the message search feature:

1. Open “All Settings”
2. Select the “Security & Privacy” tab
3. In the “Message search” section, select “Manage”
4. Confirm by selecting “Disable”
5. If the process takes too long, restarting the Element app may help.

[/UPDATE]

Alternatively, you can use Element Web at matrix.tu-dresden.de. As always, please keep the following points in mind:

• Always use more than one active Matrix session, for example on your smartphone.
• Enable the key storage and keep the recovery key in a safe place. Verify every new session.
• Never clear your browser’s entire cache while you have a Matrix session open.
