I started my game from the Steam desktop client selecting "SteamVR mode". Also i made sure that my WMR portal was running first but it still gives my the "unknown string property - dev; 0, prop: 1006" and my headset goes black. Im not sure what you meant about the "openovr_log" file. Its located in the Automobilista 2 folder and its only 4kb. Not able to open it. The opencomposite.ini file is located in my x64 folder and i made sure it has saved with the ini at the end. Also i copy pasted your textcommand "admitUnknownProps=enabled". I really appreciate your effort of trying to help me but it feels like im stuck.
