I recently noticed that all my emails from August 2023 through March 2024 have disappeared. They are missing from all folders - Inbox, Sent, Trash, all folders including everything in pop, imap accounts, and all local folders. Messages from before 8/2023 and after 3/2024 are all there. I noticed that there is a folder in Program Data called Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38. In that folder is a subfolder updates > 308046B0AF4A39CB > backgroundupdate which is dated August 15, 2023. This is the exact date that is the start of my missing emails. Could an update have caused my problem? If so, is there a remedy? Thunderbird 128.5.2esr, Windows 11 Home 24H2 build 21600.2605
