When my PC first starts up, I am able to select and open anything on my desktop. However, when I right click on my desktop, my mouse becomes the loading circle, and the context menu never appears. I also can't open any folders or applications on my desktop, but right clicking and opening files/folders works everywhere else, including the taskbar and Windows Explorer.
The most simples method, system reset, keep my files.
In my opinion, I suspect that you have some third-party software startup with system, open task manager\Startup tab to disable unnecessary software.
Another possibility, user profile issue, create a new account and boot in to this account, test Content menu.
