So Max (2018) had a viewport error where it wouldn't update the viewports, but managed to recover after a files save. However, when rendering with the AI denoiser enabled, this error prompt came up:
Internal error in NVIDIA AI Denoiser. Please report this to Corona support with this info:

Error encountered during denoising.
Unknown error (Details: Function "_rtCommandListExecute" caught exception: Failed to launch DLDenoiser post-processing stage. DLDenoiser run method failed with error -27.)


I guess it's not safe to use Max after a viewport error (probably a driver crash), reporting in case it can be resolved on your end.

And after closing the prompt with the render continuing, another one came up:

Internal error in NVIDIA AI Denoiser. Please report this to Corona support with this info:

Error encountered during denoising.
Unknown error (Details: Function "_rtCommandListExecute" caught exception: Assertion failed: "!m_launching : Memory manager launch is already active", file: C:\u\workspace\rel5.1-win64-cuda90-VS2015-build-Release\sw\wsapps\raytracing\rtsdk\rel5.1\src\Memory\MemoryManager.cpp, line: 962)


I have to add the AI denoiser works fine otherwise, no errors yet, that's the first time it happened.

Make sure you are using the newest driver and restart your PC.
Is this also happening after 3ds Max restart?

Well, it worked after a while even without restarting Max. I guess it's more a problem of Max/Nvidia than Corona, I reported it because the error prompt stated so. Thanks anyways!
