Out of memory

I cannot reopen my project, where I previously worked on rendering and animation and received output without any problems. It gives an out of memory error and vram usage exceeds 90%. Same computer, same software, same file. Why am I having such a problem?

Hello

Sorry for the problem.

May I know your current and previously used D5 version? Any recent version upgrade? Did this issue arise following the version update, or did it occur unexpectedly?

Kindly disable any other software not in use while operating D5. If the issue arises with a file that has no modifications and uses the same output settings, please send the D5 scene file to our team for testing and comparison in our environment. Thank you.
