Quixel assets not compatible with unreal engine in Fab

I’m new to unreal engine and trying to learn it making small scenes as practice and following youtube tutorials.

However, an issue I have run into is that one of the tutorials uses assets in Fab that have been made by Quixel and when I try to bring in the assets they are staying as the Fab placeholder and not downloading, I have found that the assets in Fab say they are not compatible in Unreal Engine. I would like to know if there is a fix for this or if I’ve done something wrong as I can’t seem to find any information online as to why all the assets I would like to use, are now no longer compatible despite all the tutorials I have watched having no issues with using quixel assets for environments.

Any help or advice would be great as I’m doing my best to learn at the moment.

Thanks!
