If you send us the automatic crash logs (if it crashes) or manually generated snapshots (if it's misbehaving but never crashes), we may be able to tell you the component causing the problem (whether it's in Opus or something else) without you having to narrow it down.
It's unlikely to be a problem caused by an Opus update as we don't have lots of recent threads about similar issues. Opus is working normally for most people. We need more information to be able to fix a problem which only one person is experiencing, but we can fix most problems with the right information.
