Hi @Turpster 👋

Thanks for the PR. Sorry I haven't responded until now. Change looks fine. This is all tested and good to merge?

fwiw, I can confirm that this patch works for me.
Without this patch I was unable to open up the "Installed Games" page, with it it works.

I am atm using the following nixpkgs overlay to patch it:

          (steam-library.overrideAttrs (oldAttrs: rec {
            patches = (pkgs.fetchpatch {
              url = "https://github.com/aanderse/plugin.program.steam.library/commit/e3c5b8676f0fec13bb1240e2a53ab9a7a5819322.patch";
              sha256 = "sha256-BwC8FknFxqr5lqMQ8sn8tyJLUrnCmrQCW6vT0mYnynA=";
            });
          }))

For completeness' sake: Kodi log without the patch opening up the library, I assume it is due to a ® (as in Spiritfarer®: Farewell Edition) but cannot confirm that hunch:
