Microsoft has released two new ISOs for its Windows Insiders community today. Windows 10 ISO files for the RTM Build 19044.1288 are now available for Insiders in the Release Preview Channel. Those in the Dev Channel, on the other hand, can download ISO files for Windows 11 Build 22483, which was released just last night from the active development branch.

Windows Insiders in the Dev and Release Preview Channels testing Windows 11 and Windows 10 November 2021 Update, respectively, can now clean install the latest Builds through these ISO files.
