Missing "Wine Windows Program Loader"
Actually the launcher is misplaced in Ubuntu 18+, Ubuntu made a mistake, all the other distributions based on ubuntu including linux mint inherited the bug, nobody cared to fix
Run the below command in terminal
sudo ln -s /usr/share/doc/wine-stable/examples/wine.desktop /usr/share/applications/
Now right click the windows app and click open with , you can now see open with "wine windows program loader" in the applications list.
You can remove the wine package by
sudo apt purge wine
And then install the stable version by
sudo apt install wine-stable winehq-stable
It works for me.
