Error unexpected file format

I have a .skp file that’s encountering an issue with the error message “error unexpected file format .” While searching online for solutions, I came across suggestions to use .skb files for recovery, but my attempts have also failed. Would you be able to take a look? Thank you! :pray:

Allow me to use OneDrive for file sharing (as it is larger than 16MB and exceeds the uploadable size)
