Mixed Reality Capture - errors LNK2005,LNK2019, LNK1120 when launching/packaging

Hello all,

I am totally new to Unreal and I am working on an existing VR project, trying to add in MRC function. I have done the calibration, and followed the instructions, placing the .sav file in the project folder Saved/SaveGames. I have enabled the MRC plugin. Also, I am able to launch correctly without the plugin enabled. With the plugin enabled, I get the following output of the error. Any help on this is greatly appreciated, many thanks! I have made bold the parts that I think are the most important in the output.
