If you're beta-testing Windows 11 for Microsoft, please report issues to them, not us. The purpose of a public beta is to find problems (which may affect more than just Opus) and fix them before the final release. There's no point beta-testing Windows if you don't report issues to Microsoft.
(Equally, when we do a public beta of Opus and, if you decide to beta-test it, you run into issues introduced by the beta, those should be reported to us rather than to Microsoft. That's how betas work.)
We'll only look into Windows 11 things once the new OS reaches the RTM milestone. Experience has taught us that it's a waste of time to look into beta OS issues earlier than that, as too much is still changing between releases.
