1Password extension on Brave 1.61 Flatpak sometimes will constantly lock itself upon unlocking

1Password extension on Brave 1.61 Flatpak sometimes will instantly lock itself upon unlocking. Restarting the browser sometimes fixes this, sometimes it doesn't.
This is without the desktop application installed.
Toggling the "integrate 1Password extension with 1Password application" makes no difference.
