Thank you for your feedback. With that information we know this is probably a regression introduced on 5.4.0-56 and that it is fixed on mainline kernel.
The current linux version in focal-updates is 5.4.0-65.73, could you please try it? If this version is still broken, it would be also be good to test the version in focal-proposed (5.4.0-66.74). Both of these version have several bug fixes. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.
Please also double check if you have the linux-modules-extra package installed for all of the tested versions.
