I have a site running PHP 7.4
In Wordpress Health Status it says Critical issue:
Your site is running on an outdated version of PHP (7.4.33),
which does not recieve security updates.
It should be updated.
But when I try PHP 8.2 or higher there is an immediate error.
No website at all. What could be the cause?
You need to run wp in debug mode to get more info. Could be a plugin.
Did you follow the VM docs to multiple php versions?

Put it back to 7.4 and update all of your plugins, then change to PHP to 8.3
There is a good change you do not have the latest version of wordpress becasue only the very latest ones support PHP 8.2/8.3
Obviously the plugins need to support 8.3 but usually they will just error if incompatible.

Thanks. In debug there was a lot to check.

Is it possible to make a completely new test site with the latest Wordpress, and then just copy certain files or directories to a site that doesn’t support php 8.3?
Or is that just wishful thinking?
Is the issue a plugin?
Plugins are just normally folders in the plugin directory so that pretty easy to copy over.
Have you tired just disabling all the plugins and seeing if that fixes the issue then re-enabling one at a time to find the problem plugin.
