LivingDoc: Assembly not found

I have installed the LivingDoc CLI tool by running

dotnet tool install --global SpecFlow.Plus.LivingDoc.CLI

When I run the commands specified in the docs, I get the following error:

C:\Projects\SpecFlowCalculator\SpecFlowCalculator.Specs\bin\Debug\netcoreapp3.1>livingdoc test-assembly SpecFlowCalculator.Specs.dll -t TestExecution.json
Error:
  An assembly specified in the application dependencies manifest (Microsoft.NETCore.App.deps.json) was not found:
    package: 'runtime.win-x64.Microsoft.NETCore.App', version: '5.0.17-servicing.22213.14'
    path: 'runtimes/win-x64/lib/net5.0/System.Linq.dll'

Any suggestions on how to fix this would be appreciated
