Might happen when you uninstal the DCH driver
AFAIK Nvidia DCH (UWP) control panel has to be downloaded from Microsoft Store.

Yes, that is one of the links, but sometimes the normal control panel doesn't get installed after a DCH uninstall and standard install.
Or at least that is what I gathered from reading some of posts on the issue. I might have misread though

LAV filter shows which decoder it uses and it tells cuvid.
What version of LAV and what player are you using? I aim to duplicate your case.

MPC-BE (x64 flavor, just remember to disable internal filters) and LAV Filters latest nightly but I think stable ones should work too.

Thank you.

How do I disable internal filters and why?

View >> Options >> Internal Filters
The why?
If they are not disabled, MPC will use the internal filters and not the external LAVF

Some builds of 435.27 were broken

Also note that these prerelease drivers were released 2 months ago
Official drivers are still on 431.xx

That's ancient history. 435.80 is broken.
