GetThreadContext failed error, happens only in play mode, only on one single project?

I've read about these GetThreadContext errors happening because of antivirus software, however testing things I found out that the error I got only happens with a certain project, even when antivirus software is turned off.

At first I thought it was a script issue, but removing all potential troublemakers from the scene and starting the game still results in a dozen of those error messages popping up.

Any idea as to why this would happen?

EDIT: making a new empty scene in this project(only one camera in it, as it is by default), still gets me the error, so it is definitely not script related. Why is this only happening on a single project?
