I was getting exactly the same. I ran it in VS2017 debugger which returned an exception with return dli.pfnCur; in delayhlp.cpp. I continued anyway and had something similar at line 205 of ProteusOvrAvatarManager.cpp. The bit of code around it didn’t look too important to my untrained eye so I commented out lines 174-214, rebuilt and ran. It got past 73%, held at 95% for AGES and then loaded. No idea yet if everything actually works but it’s loaded so that’s a start.
