We'd need a lot more information please, such as
- Which denoiser? The NVIDIA AI denoisier, or the final quality denoiser?
- Just what was the error that you are receiving? Not a lot we can say unless you let us know what the error was and said :) You can always screen grab it, rather than write out the text.
- If the NVIDIA Denoiser, is it unchecked for IR as well as unselected for the final render? (There are two places you can set it to be used)
- Which OS, Windows or Mac?
- Is this every scene, or just one particular scene?
This page gives a good guide on the kind of information we need in order to be able to look into and resolve an issue:

Thanks!
