Bottles stopped working after NVIDIA update

[Mongo42]

Hi all,
Last night, I updated my kernel (Ubuntu 20.04; kernel v5.15.0-144) and along with it several NVidia dependencies. Before the update Bottles was working brilliantly, but afterwards the Bottles GUI will load, but any games are now DOA. Usually, when there is an NVIDIA update, I just have to run 'flatpak update' and then all is well with the world again. This time, when I try the flatpak update, I get a whole bunch of the following:

~> Your Command, Oh Master? flatpak update
Looking for updates…

I tried to do a flatpak repair (w/ root privileges), which completed successfully, and said that all was OK. The update command still gives the same stuff. Just looking at the text, it looks as if the repository is down. Is anybody else seeing the same thing? Any suggestions as to what I am missing? Thanks!
