@osman, is the bug still happening for you? If so, could you try with the latest version please? Release v1.7.10 · laurent22/joplin · GitHub When doing so please open the dev tools first (from the Help menu), then try to replicate the same steps to cause the crash.

Normally with this version it shouldn't crash, but it should display an error in the console, perhaps providing more info as to why it's happening. If you manage to get this error message, please could you post it here?
