I am experiencing a symptom sometimes when I delete a message in the Thunderbord email client (in any folder), all messages disappearing from all accounts in the entire Thunderbird including Inbox, Drafts, Trash, Sent and everything else. All folders become empty. The messages are not deleted, just not showing. Using the Trash icon of Thunderbird or pressing the delete key are the same. There is no way to display the messages again except to close and re-open Thunderbird. After that, everything return to normal. This does not always happen, about 75% of time. Thunderbird version is 128.6.0esr (64-bit), Windows 11 but the same also happened on previous versions and Windows 10.
