Keyboard Not Working In Safe Mode?

Currently on Microsoft Windows 10 Pro Build 17763. I noticed (not exactly sure how long it's been like this) but when I am in "safe mode", my keyboard is on, connected fine, I can type just fine in, say notepad and windows powershell for example. However, at a "windows run box" I cannot type anything, keyboard doesn't seem to work. My mouse works fine throughout.

I have tried deleting the device drivers thru device manager and reconnecting to "plug and play" again and no help. I have tried an "in-place windows 10 upgrade" and no help.

Everything works just fine in non-safe mode.

Thanks in advance (I have attached my registry device settings for reference as well)

I will try out your suggestions when I return from work later today. Thanks.

I do not use a desktop shell. Typing Windows key + x works, I can type. Right click the start button and choosing run, I can type. The On Screen Keyboard works too.

What I realized is the only place I type and no letters/output is produced is the Cortana search box.
