See Announcing Windows 11 Insider Preview Build 26200.5510 (Dev Channel) | Windows Insider Blog for known issues.
From the Release Notes: “Starting today, the Dev Channel is jumping ahead to receive 26200 series builds. This means that the window to switch from the Dev Channel to the Beta Channel is closed and once Build 26200.5510 is installed. If you are in the Dev Channel today and still want to switch to the Beta Channel at the last minute, when Build 26200.5510 is offered you can pause updates in Windows Update and switch your channel to the Beta Channel and un-pause updates.
These 26200 series builds are based on Windows 11, version 24H2 and will contain many of the same features and improvements as the 26120 series builds that will continue to be released in the Beta Channel. Over time, we will be making behind-the-scenes platform changes in these builds and these builds may have different known issues because of those changes than what we’re flighting to the Beta Channel.
In the case of Build 26200.5510 today – this build contains the same features and improvements as Build 26120.3576 released previously.”
