An error occurred during the mutation test run

[dupdob]

Thanks the problem is revealed here:
[11:29:41 DBG] The specified version string '...0' does not conform to the required format - major[.minor[.build[.revision]]], SourceFile(Y\XWorker\XWorker\obj\Debug\net8.0\XWorker.AssemblyInfo.cs[981..987))

The version number is clearly missing. I suspect this is because the version number is defined via some environment variables or parameters that were not captured during analysis.
A work around would be to manually set said version number.
We need you to explain how the version number is set up during build to understand if there is a way to capture this somehow.

Note: Strykes does not mutate any ....assemblyinfo.cs file, even if the log talks about rolling mutations back, this is the default logic when a compilation error happens.
