Hey, @wohu233.

This might be a windows-related issue. This issue will remain open while we look into it.

Thanks for the feedback here - that's always super helpful. We do naturally try to keep everything updated, but, as you might imagine, in some cases, we also do have to prioritize some updates over others. This looks to be one that won't have high priority. We now have a note internally on it - closing this issue here. Thanks, Team
