Message search can never be enabled in some situations

[aneverhopefulhelper]

It seems somehow the passphrase in keytar can get out of sync with the actual database password. Element doesn't appear to be able to recover from this situation, leading to message search just not turning on. We should detect a passphrase mismatch and probably just delete the database and start re-indexing (probably warning the user, lest they end up in a cycle of it re-indexing without their knowledge every time the app is restarted). According to this report, the spinner keeps spinning too, even after it fails.

Original report below:

Steps to reproduce

1. Trying to enable message search in Element desktop

The loading/processing wheel spins for hours and does not enable message search

Operating system

Linux Mint

Application version

Element version: 1.9.2 Olm version: 3.2.3

How did you install the app?

https://packages.riot.im/debian default/main amd64

Homeserver

semi.social

Will you send logs?

Yes

In the logs I am seeing EventIndex: Error initializing the event index {"message":"Error opening the database: DatabaseUnlockError("Invalid passphrase")"} I suspect this is related, however, I am unsure how to fix this, if there is a file or something I can delete or modify or some setting I can change then I am willing to do so, but right now I don't know what to do.

You could try manually deleting the event index (~/.config/Element/EventStore). I'm going to repurpose this issue into Element not handling the situation where the passphrase from keytar doesn't match the passphrase on the database.

You could try manually deleting the event index (~/.config/Element/EventStore).

Do you mean delete everything in there or just files called .store? Because I tried deleting everything (after backing it all up, just in case) and then when I tried to enable message search again I got this error in the log: EventIndex: Error initializing the event index {"message":"Error opening the database: IndexError(IOError(IOError { path: None, err: Custom { kind: Other, error: "Invalid MAC" } }))"}
