There all my output settings are correct. I was able to render this scene last night. And after come to this scene without any changes I couldn't render because this ERROR!

Your RPR is stay in deep alpha stage. Absolutely not usable.

Ok, It seem I found the problem. There RPR couldn't forget patch link to Background override file while this option was uncheck!

I uncheck "Background override" while this error stay. It was need to force delete link to file even option was uncheck.

You should put some more checking error options to your code.
