Corrupted file

After updating D5 RENDER, my render file was corrupted, I need to deliver the project to the client urgently, I need a solution.

Hi! Really sorry for this. Which version did you use before you updated? Which version are you currently updated to? Are there any error reporting popups now? If so, please show us.
BTW, we suggest you to share your system info with us. If your system info shows that your graphics card driver version is too old, please update the driver.
