The ucrtbase.dll issue is a windows issue, specifically an issue with the Microsoft C Runtime Library. SketchUp needs access to that library to run, but it seems a recent Windows update may have broken their ucrtbase.dll as well as other kernel level objects.

You can run the System File Checker tool to validate these kernel files. Here’s how:
