Removing and Re-installing Unity' VSCode package from the package manager.Changing the editor in Preferences>External Tools, and Regenerating project files for each option.Restart/reboot Unity/VSCode/Computer/etc.I see the issue in Visual Studio 2022 (preview).I have also verified that Preferences>External Tools has VSCode as the editor, and tried regenerating project files. sln files, while Unity and Hub were off, and had Unity rebuild them. They were attached and everything worked fine until the issue presented itself. My assembly definitions have the correct dependencies.Everything is up to date, including VSCode, Unity's VSCode package, and VSCode extensions (Debugger for Unity, C#, etc).Some quick things to note, to skip some common solutions: Also, I noticed that other packages, such as Odin Inspector, are having the same issue. Other scripts and namespaces work fine, and assembly definitions are untouched from before the issue began. However, I can not roll either of these back, and check if it solves the issue. I believe the issue came either when I updated Unity, or Unity's VSCode package in the package manager. A few days ago, VSCode stop recognizing all Unity Namespaces except UnityEngine.
