Concatenate Scripts - option

When publishing, using the Concatinate Scripts option creates a blank screen.
It’s been about a year now, precisely May 26, 2020, since I published this project last.

I’ve opened the project to fix an issue I found on a Nokia phone in ie. But I notice when I publish with ‘concatinate scripts’ checked, the occurs errors. I also noticed just playing it on the Editor with the option of ‘concatinate scripts’ there is different issue, but without ‘concatinate’ it works reasonably well (It’s been a year, so I expected some issues)

Do you get any errors in the browser?
Are all the scripts preloaded?
Can the build be shared for someone to look at?
