The Windows team at Microsoft has discovered a significant bug affecting the Canary build, which has led to the delay of several Insider builds. This bug impacts essential functionalities such as Bluetooth and Wi-Fi connectivity, USB accessory connections, and the onboard camera for Windows Hello. Brandon LeBlanc from the Windows Insider program described the bug as "really bad" and noted that it arose from a specific code change in newer builds not yet released to Insiders. Microsoft is currently working on a fix and hopes to deliver a new build to the Canary channel by the end of the week. The situation emphasizes the company's focus on quality control to prevent flawed releases from reaching users.
