Assertion failed on expression: 'm_Buffer != NULL'

Hey guys.

Im strugglin with a huge problem. On monday i decided to start with the MS HoloLens Tutorial 101 (i did it already half a year ago) to refresh my mind.

After building the project in Unity and starting in VS2017.4 it crashed. I tried a lot of combinations between Unity versions and VS2017 versions. Sometimes, it worked when i started it fast enough after reboot for one time... the second attempt failed again...
Every time the same failure. I began to think it has something to do with Hyper-V, so i deinstalled Oracle Virtual Machine -> same problem. After all,. i decided to format c: -> same problem... More than 20 hours of work and i couldn´t really start until now.


Would be so happy, if someone could help.... it is for my master thesis...
