I would try reinstalling after reverting to the previous daily (which I think you have already done), just to see. Do let us know if you get any errors, and if the Denoising checkbox can be checked on and off after a render is complete (this lets us know if denoising actually ran or not, it will be greyed out if there was no denoising). If time allows, a video of the process, from setting the chosen denoiser to rendering a scene, could help. You could send in any scene that has the problem too, so we can have a look through the settings and test that specific scene here (even the plane and teapot scene, if that is giving the same problem :) )
