[xUnit.net + dotCover meta-runner] Error "Incorrect 'TargetExecutable' value"

TeamCity Professional 2018.1 (build 58245)
The error in "Step 1/1: Install Test runner, Create config, Run tests, Update coverage (PowerShell)":
[Step 1/1] Incorrect 'TargetExecutable' value 'C:\TeamCity\buildAgent\work\6fc5b5e66f19d062\xunit.runner.console.2.4.0\tools\net452\xunit.console.exe C:\TeamCity\buildAgent\work\6fc5b5e66f19d062\xunit.runner.console.2.4.0\tools\net46\xunit.console.exe C:\TeamCity\buildAgent\work\6fc5b5e66f19d062\xunit.runner.console.2.4.0\tools\net461\xunit.console.exe C:\TeamCity\buildAgent\work\6fc5b5e66f19d062\xunit.runner.console.2.4.0\tools\net462\xunit.console.exe C:\TeamCity\buildAgent\work\6fc5b5e66f19d062\xunit.runner.console.2.4.0\tools\net47\xunit.console.exe C:\TeamCity\buildAgent\work\6fc5b5e66f19d062\xunit.runner.console.2.4.0\tools\net471\xunit.console.exe C:\TeamCity\buildAgent\work\6fc5b5e66f19d062\xunit.runner.console.2.4.0\tools\net472\xunit.console.exe'

The problem is in the following code:

$xunit = Join-Path $workingDir "xunit.runner.console.*\tools\$xUnitExe" | Resolve-Path
    
if (-not $xunit) {
    # Try finding xunit under framework specific folder
     $xunit = Join-Path $workingDir "xunit.runner.console.*\tools\net4*\$xUnitExe" | Resolve-Path
}

When $xUnitExe is "xunit.console.exe" (as specified in readme.md) then Join-Path command will return multiple results for the "xunit.runner.console.\tools\net4\$xUnitExe" path.

As a fast solution can be specified the folder name for "Xunit Runner Executable" param:
"net461\xunit.console.exe".
