I sent a bug report and was told that I needed to update from KDE Plasma version 5.18 to 5.24 as the bug had been fixed. I update everyday almost, whenever updates are available. Tried to find a way to update just KDE Plasma, but found none. Is there a terminal command to do this? Obviously just update is not doing it for me.

Ubuntu 20.04 LTS uses the LTS version of Qt5 (5.12). You have received all upgrades that are possible with that LTS version of Qt (which was 5.12.3 if I recall at release; and now sits at 5.12.8).
For users who want stability; they can remain on the LTS release, using LTS libraries & toolkits - at cost of using older software.
To upgrade to later Qt5 & KF5 (KDE Frameworks) as required by newer KDE Plasma versions, Kubuntu offers that via upgrading your entire stack using non-LTS releases, ie.
- Kubuntu 20.10
- Kubuntu 21.04
- Kubuntu 21.10
These later releases have newer KDE Plasma, and the required later (non-LTS) toolkits/libraries of Qt5 & KF5.
