Avermedia device occupied error

I'm trying to get my Avermedia LGP working on my Windows 10 machine.
But when I try to preview the stream via RECentral I get an error that says:

Device is busy
Device occupied. Please close the software in conflicts first.

The LGP is not at fault because this works perfectly fine on my Windows 7 machine.

Things I've tried:
Rebooted the system
Uninstall and reinstall the program and drivers
Tried OBS
Different USB cables in different ports

Any hints as how to fix this?
