Hi there,

I attempted to reproduce your issue and was unable to do so. This error indicates a timeout occurred during query execution. This may be related to a resource (high CPU or Memory) utilization.

We use GitHub issues as a place to track bugs and other development related issues. If your issue persists, please write us back using our “Contact support” form located on our Help Center (https://bitwarden.com/help/).

You can include a link to this issue in the message content.

Alternatively, you can also search for an answer in our help documentation or get help from other Bitwarden users on our community forums (https://community.bitwarden.com/c/support/).

The issue here will be closed.

Thanks!
