Folder, Threads pane completely empty

Debian Bookworm, TB 115.5.2 (64-bit)

In the Mail toolbar the Folder pane and the Threads pane are completely empty, no folders, not even icons or text is visible. Message list display option and Quick Filter buttons are visible but not working when clicked. Same in --safe-mode, and after i cleared the cache. Address book, Tasks, Calendar, Chat seem to be complete though. Settings tab works too.
