Hi,
Thank you for sharing the issue and I am very sorry about the crashes!
From your description, it would be a bit difficult to find out what is causing the crash. If it happens again with a Bug Reporter, could you share the BugID number with me for analyzing?
Moreover, is there a specific way to reproduce the crash, or it just happens randomly, with any given file during Teamwork operation?
Looking forward to hearing from you!
Best regards,
Minh
