Issue Description

OS: Debian Buster Mono JIT compiler version 6.10.0.104 Microsoft (R) Build Engine version 16.6.0 for Mono; 16.6.0

Building a solution with multiple projects only works when using 1 CPU

msbuild /m MyProject.sln --> fails msbuild MyProject.sln --> works

Steps to Reproduce

Create a solution with one specflow project and some other projects.

Build the solution on linux with mono:

msbuild /m MyProject.sln --> fails msbuild MyProject.sln --> works (but only uses 1 CPU)

Is is important to call msbuild with the sln file (with just the .csproj file it works)

The error message is excatly what we also see in the issue https://github.com/SpecFlowOSS/SpecFlow/issues/2325#issuecomment-864540824
