project manager unknown error when Consolidating

So i've been really breaking my head over this issue. 

When consolidating a few seuqences in a clients project we get the Unkown error from project manager.

I have no clear answer as to how te sequence is build since the client has done this. 
However i will try to explain as much detail as possible  
Source footage: AVC 100 

Steps to Consolidate: 
See screenshot aswell
- open project manager 
select the sequence (which is already selected) 
- Select sonsolidate and transcode 
source : Individual clips 
Format  : MXF OP1a
Preset : match source - AVC-Intra 

Destination: Big shared storage drive which is connected with 10GB fiber 
- Options: 
Exclude unused clips
Include Handles: 25 frames or 30 frames ( tried both) 
Rename media files to match clip names 

Steps ive taken to troubleshoot so far: 

Copying project 
Copying sequence and pasting in new project 
Consolidating to a different codex 
checking for special characters 
Tried it on a VM machine and on a bare metal machine.  

How all sequences are build: 
They use regular avc 100 video footage 
MORGT footage. 

Error message we receive 

project manager settings:
