Start Menu in Windows 10 suddenly closes when right clicking on username

When you right click on your username in Windows 10, at least for me, the whole Start Menu suddenly closes (by either waiting around or moving your mouse around. you also can't click on anything) Why this is happening is beyond me.

I know I could sign out using +X or switch using using Ctrl+Alt+Delete but I think it's really handy being able to easily switch to another other user (in my case, a user called "Development"). Basically. I want to fix this and I want it to work.

I've found absolutely nothing remotely related to my problem online, and it's happening on newly created users as well.

ShellExperienceHost.exe crashes every time. The event log is below:
