Unexpected File Format SU 2024 SKP and SKB file can’t open, HELP!

Hi, my skp file has been corrupted i am using sup 2024. Can anyone assist me on this? I have the skb file but it is still the same unexpected file format. Thank you. I really hope the file can be restored.
pyc88888.skp (2.0 MB)

the skp certainly doesn’t open, can you post the .skb ?

Thank you for your attention. I tried the SKb file but it didn’t work.

Sorry to hear that… Hope you didn’t lose too much work…
