Hi, @kevin1. Please take a look at this support guide:
Also, there is a big red flag that a running process not being exited correctly is the root cause:
10:15:29 AM: Webpack Bundle Analyzer is started at http://127.0.0.1:8888
10:15:29 AM: Use Ctrl+C to close it
If I was a gambler (which I am not), my money would be on that above being the process still running and which prevents the build from exiting.
The solution is to make certain that process is shut down when the build is complete.
If this doesn’t work, please let us know what you tried and/or if there are any questions.
