Corrupted LumenRT file

Recently when trying to open a scene I created I get an error saying it can't open and was likely corrupted. Unfortunately my .bak file was too long ago. Is there a way I can fix the file? Can any of you open it?

When trying to attach it here it wouldn't either just saying "error". So here's a link to a copy I pasted to google drive:

drive.google.com/.../view

Thanks!!!
