Microsoft has rolled out Windows 11 Build 22621.457 (KB5016695) to Insiders in the Release Preview Channel.
This build is for insiders on Windows 11, version 22H2, which is tipped for a mainstream release on September 20 — a week after that month’s Patch Tuesday (which falls on the second Tuesday of each month). The Preview Channel is the most stable preview behind the Dev Channel and Beta Channel.
