Public bug reported: I upgraded from 440 to nvidia-driver-450, and found that suddenly WINE, Steam, and other 32-bit OpenGL apps would no longer work (64-bit OpenGL apps worked fine). This was tested with the current version: 450.57-0ubuntu2 on groovy.
Completely removing nvidia* packages and re-installing did not fix. The issue is compounded by the fact that nvidia-driver-440 has been replaced with a transitional package pointing to the 450 version, so backleveling is not possible. The package also recommends "libnvidia-compute-450:i386 libnvidia- decode-450:i386 libnvidia-encode-450:i386 libnvidia-ifr1-450:i386 libnvidia-fbc1-450:i386", none of which are installable. libnvidia-gl-450:i386 is not installable: Package libnvidia-gl-450:i386 is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source However the following packages replace it: libnvidia-common-450 libnvidia-common-450 does not contain the 32-bit files, and there is no 32-bit version of that package. Extracting the 32-bit files from the official nVidia package and placing them in a directory linked with ldconfig fixes the issue.
