Can't Use ANYTHING in 4.24

Everything I want is for older versions so the whole thing is useless. Most of the assets from the marketplace are not compatibilie with the current version.

You can install an supported version of the editor to load in the assets and then migrate them to a new 4.24 project though there’s a chance that some things won’t work due to updates between versions.
Or you can wait for stuff to add support for 4.24
