UE5.0.1 crash's when I open select UE 5 preview files with lidar data in it , please help

Hi all,

In a bit if a pickle at the moment. All the files that I made using the lidar plugin on UE 5 preview now won’t open. It just crashes. I can’t even roll back to the preview version on UE as it is gone. I can rebuild the file and that works but that means I lose everything I’ve done so far. Any ideas?Thanks.
