If realm has been migrated to new schema version while opened in the Browser, most likely browser crashes. The issue is related to bindings which doesn't handle schema changes when using dynamic API.
There are cases for this issue: local and synced realms, also related to https://github.com/realm/realm-browser-osx/issues/296.
