npm start is throwing error with exit code 126

Question

So im working through a course on Pluralsight which has with a folder containing files required for the course. Part of the course requires me to install and run npm. It installed with a few issue, which required me to run npm audit fix. The dependency issues cleared but Im still having issues running npm start. Below is the console's response after running npm start and after that, separated by hash tags is a copy of the log output. Has anyone come across this and/or could anyone help with this?
