Thunderbird 102 irrecoverably destroys messages content overwriting them with random content from other messages
A critically important bug!
Messages in local inbox (it is possible that the bug occurs in other or all local mailboxes too) get completely overwritten by Thunderbird 102 with parts of neighboring messages or by truncated content from the same message. The damage is irrecoverable and irreversible - original content is permanently lost. Message subject still appears in the list of messages, but in the message view pane there is no subject and no message, or just random HTML source parts of another message. Destroyed messages are OK after downloading and display correctly until overwritten under unclear circumstances. In one occasion, there was a monster message created by merging 2 messages into one - with a subject line and top part of the message header from the first message and bottom part of the header and broken content of the second message (3-rd attachment). "Folder properties"/<Repair folder> does not restore the lost content.

It was impossible to upload a 3-rd attachment to the question, so I add it as a reply here.
I'm having the same problem with POP3 accounts. On messages that are corrupted, I see no message header in the view pane, and content of e-mails is either for the wrong message and/or not 'decoded' and displayed correctly (see attachment). Could this have something to do with POP3 being "implemented in JavaScript" according to the 102 release notes?
Other possibility: Message Filters. Reason being that if I can see messages that should be filtered still in my Inbox. So, I right-click and do Properties -> Repair on Inbox, and then run filters again - but then I have 2 copies of all those messages in my subfolders, and some of the non-filtered messages in the Inbox disappear along with other non-filtered messages.
Dunno if any of that is a clue, but there you have it. Thanks!
I rebuilt the indices of all folders, then restarted Tbird for good measure. Still no dice. So, it's not just corrupt index files, I reckon.

Do you have quarantine enabled in Settings > Privacy > Security > Antivirus ?
Yes, Settings > Privacy > Security > Antivirus is enabled. Should it be disabled and how does this influence the bug, since the destroyed messages are not quarantined ones?
Yes, try disabled and report your results please.
Disabling quarantine didn't help for me.
Does 102.0.3 resolve your problem?
