I see this bug still in plasma 5.16.2 (already in 5.15, but did not report until now).
See screenshot attached (why_reopened.jpg)

Is anyone able to reproduce this issue in Plasma 5.18 (the latest LTS version) or 5.21 (the latest released version)? Seems like it might have gotten fixed, judging by the lack of chatter since it was opened?

Screenshot shows the  issue using latest openSUSE Tumbleweed versions (Framework 5.81, KDE Plasma 5.21.4, QT 5.15.2)
Comment 11 Nate Graham 2021-04-12 17:20:33 UTC
Thanks.

Is anything printed to the console when this happens? You can see by running `plasmashell --replace` in a terminal window and then clicking on a grouped task.
Comment 12 Robby Engelmann 2021-04-12 18:16:34 UTC
I got:
file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/Task.qml:396: TypeError: Cannot read property 'count' of null

However, this time it was not reproducible, I do not know how to trigger it consistently.
Comment 13 Nate Graham 2021-04-12 20:52:52 UTC
Hmm, seems related, though not the exact thing. Somehow the underlying data model that the UI wants to use to generate the UI is reporting a thing as null when it should be an object with a `count` property.

This was fixed a while ago.
