光标在代码编辑器中的 Visual Studio 2019 中断开

Question

When trying to move the cursor in code editor to the right / left / down / up using the arrows, the cursor does not move. Instead, Visual Studio switches from the code editor to changing the size of the text in the editor (click on the left arrow), changing the project (click on the up arrow), starting code cleanup (click on the down arrow), nothing happens when you click on the right arrow. In addition, all hotkeys don't work (F5, Ctrl+S, Ctrl+B, etc.) Delete and Backspace do not work too, but Ctrl+Z works.

All this applies only to Visual Studio 2019, everything works fine in other text editors

I didn't change any settings, everything worked fine yesterday. What could be the problem and how to fix it?

What happens when I Click on the left arrow

What happens when I Click on the up arrow

What happens when I CLick on the down arrow
