Sketchup Shop is slow and not responding

I recently purchased Sketchup Shop for a personal home design project. I recently figured out how to purge unused materials to reduce the file size. However, this has not resolved the problem of the program being slow and unresponsive. I am constantly getting error messages such as, “Sketchup not responding” or “long running script”. I am using Windows 10 with NVIDIA GeForce GTX 1050 Ti and a very fast internet connection. Is there anything else I can do to make this program I paid for useable because at this point it is not? The average file size where this is a problem is 70mb. I feel like I am sitting and spinning more than I am working. Any suggestions would be greatly appreciated. Thank you.
