Nightly build does not run

Operating system: Windows 10
Slicer version: 4.10
Expected behavior: Run successfully after build
Actual behavior: Closes with error that certain .dll files are missing just after appearance of logo. Specifically mentions CTKWidgets.dll, CTKVisualizationVTKCore.dll, CTKQtTesting.dll was not found.

You need to start Slicer with Slicer.exe.

If you did that and you still get errors then it means that the DLLs are actually missing, most likely do to a build error. Check your build log.

A post was split to a new topic: Simple Filters module do not have any filters in latest nightly version

It was a build error. The .dll files were actually missing. Rebuilding solved my problem.
