Ran into the same error... - as I changed to the recommended 2018.2
version on the compatibility guide. I went through the "fix" above, but
still had the Unable to load DLL 'OVRPlugin'...but... I had also
switched the back end scripting from Mono to ...
had the same issue - tried factory reset - no luck. Took it into bestbuy
and the samsung tech futzed around with it. Fix was to disconnect the
adapter on the headset and clean the contacts.
