Hi, good day!
Since this is a new PC, could you let me know
What is the make and exact model of the PC? Press Windows key + R to open Run then type msinfo32
Press Enter. Please take a screenshot of the resulting window and post it in your next response.
Which Windows 11 version and OS build are you running? Press Windows key + R, type winver, and press Enter
Does the same thing happen if you press Ctrl + Alt + Delete and then select Task Manager? Also, do apps open normally from the desktop or File Explorer?
Please try to run SFC and DISM to check for any system errors and corrupted files. https://support.microsoft.com/windows/using-system-file-checker-in-windows-365e0031-36b1-6031-f804-8fd86e0ef4ca Restart your computer
