Scan freezes when scanning SharpVectors-1.8.2 library

### Description
I downloaded the package from GitHub to a local directory.

I run the scan several times with several excludes and -n -1, -n 1 and -n 2 option
E:\scancode-toolkit-v32.0.8\scancode -clpeui -v -n -1 --ignore "*.java", --ignore "*.settings" --ignore "*.csproj" --ignore "*.Designer.cs" --ignore "*.resx" --json-pp e:\Libraries\SharpVectors-1.8.2.json e:\Libraries\SharpVectors-1.8.2\Source

Scan feezes when scanning an assembly.cs file or another cs file

### How To Reproduce
