What do you mean by "copy over the cache folder". There should be no need to do anything like that.

Anyway - what version of Moodle is this?

You should also check that you definitely have file cache/classes/version_wrapper.php.

I think you might be lucky if anybody here knows anything about Render Cloud. I certainly don't

However, they seem to be looking for the command to start your web server. Which web server are you using?

I'm guessing that this is some sort of container service, so I would expect you to have containers for nginx, php-fpm and so on. But... I could be completely wrong.

I don't know anything at all about XAMPP, sorry. However, I know a lot of people use it for Moodle so it's surprising that this is a problem. The Intl extension is a requirement for Moodle but I would certainly check it is enabled in your XAMPP system.
