This is kind of hard to explain, so please see the attached Before and After videos. In these videos, I'm using a brand new .NET 6 console app.
In the Before video, the Telerik UI for Blazor extension is disabled. After I type `Console` and hit the period, I see intellisense like I expect to.
In the After video, the extension is enabled. I'm typing the same thing and hitting period, but something interrupts the period keystroke, and it never appears. Instead, it just closes the intellisense window.
I used a new console app as an example, but it's happening in all projects. It's also happening with other keys like semicolons, spaces, and tabs. It's causing a huge amount of typos and making so I often have to hit keystrokes twice in order for them to register.
I tried doing a full reinstall of Visual Studio. Everything's fine until I install the Telerik extension, then it starts. If I disable the extension, the issue goes away.
