wine --version
it looks like wine32 is missing, you should install it.
as root, please execute "apt-get install wine32"
wine-5.0 (Ubuntu 5.0-3ubuntu1)

Not a KDE issue in any way whatsoever, nor a Konsole one either.

Code: Select all

sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main'

You added a repo that is specifically for *buntu Bionic 18.04 on a Focal 20.04 system, which causes conflicts as there are different dependencies between distro versions.

Here are the correct and official instructions for adding the WineHQ repos, and also for properly installing wine:
https://wiki.winehq.org/Ubuntu
Note there is no mention of 'wine64', as this is but one component of many that are installed when following the fairly simple directions given on that page.
You will need to remove the incorrect repo you added.
