Xbox Series X Wcml Simply Unplayable After Last Update

Have The WCML South route installed on my Xbox Series S the only DLC Installed with no Content from Creators Club at all and still it crashes with nothing on my console apart from this route, what on earth is going on??

Was running fine before the update on Tuesday with other routes and DLC Installed!

After The Update it has become unplayable!!

What on Earth have you guys done to make the route even worse????

And Before you all ask yes I'm playing in HD Not 4K either
