Windows 10 IoT LTSC 2021...'has reached end of support' warning (?!)

Hi guys! So...yeah, I have a W10 IoT LTSC permanently activated via massgrave getting this warning. Any idea what's up? Shouldn't it continue chugging along for a good few years more?

EDIT: This is a VM, as I run mainly Linux on everything if I can avoid it. I'm just feating there might be more like this.
