Application links are no more showing up

Hi since upgrading my nixos system, seems like all links to winapps are gone.
I re-setup winapps with the script:

 ⚡tobias ❯❯ winapps-setup

INSTALLATION COMPLETE.

EDIT: I'm running nixos-unstable and use without flakes.

The apps like word, excel also don't appear in the "Open with" menu anymore.

@oskardotglobal Any ideas on how to resolve this?

Thanks.

I just checked, executing the exec command inside the .desktop file in /usr/share/applications seems to launch for example excel just fine.

But somehow they don't get picked up by nixos.

using gtk-launch /usr/share/applications/excel-o365.desktop results in:

gtk-launch: no such application /usr/share/applications/excel-o365.desktop

yet the file clearly exists.

Note:
Do not set up using mode System instead of user, thins breaks NixOS installation
