Win10 does not shut down, shutdown.exe not working

So for a few days I can't shut down Win10 anymore. I've searched around quite a lot but haven't found a solution that works, so posting here as my last resort:

1. The shutdown button on the win10 menu does nothing at all. I click it, nothing happens.

2. I tried shutdown via shutdown /s /t 0 (and a few other arguments) but nothing happens at all. I can just ctrl+c to exit out of the shutdown program.

3. I logged off and used shutdown from the login screen. This gets me to a 'shutting down' spinner, but again, nothing happens and I have to hard reboot after a while.

Now I tried all the things that are usually recommended, ie disable hibernation (did that a long time ago) and disable fast boot. I ran chkdsk, sfc and dism, both from within windows and from the boot terminal and no problems can be found. I'm not on an intel chipset so cannot try https://superuser.com/a/959619/727973

--EDIT: It will shut down properly in safe mode --

Hoping someone has come across something similar before and can point me in the right direction, I really want to avoid setting up windows again ...
