They got evicted from the Boulder, CO office https://arstechnica.com/tech-policy/2023/06/judge-ruled-twit... and the Singapore office https://observer.com/2023/01/twitter-employees-evicted-singa... I know they were sued in San Francisco and London as well, but I can't find how those suits turned out.
Edit: Bloomberg says they finally paid rent in London and the suit was dropped. https://www.bloomberg.com/news/articles/2023-05-03/twitter-s... (https://archive.is/3e0Eh)
Edit2: A lawsuit in Oakland and a different one in SF were "dropped" and no one seems to know why. https://therealdeal.com/sanfrancisco/2023/07/03/twitter-rent...
