D5 closes when opening a file

Hello.
D5 closes when opening a file (around 40 procents).
Back up files also cannot open.
What can I do?

Thank you!

Did you place too many assest after the last editing? How are the VRAM and RAM when you open it? can you send the scenes and logs to us for troubleshooting?
