Unknown error while exporting in v4.16.3

Hi, I created a project with a friend and tried to export it. It fails instantly with the following error log. I have substance plugIn enabled. When it is enabled the log is in Error3.txt File. When I disable substance plugin the packaging goes for some time and then I get this error in the file Error2.txt (Uploaded File Name). I need substance plug in because i have many materials from it being used. Can anyone help? Many thanks in advance.
