Following several weeks of working on this issue off and on, and posts about this or that correct settings in the rc files which did not resolve the issue. The thing was that prior to the updates everything was working fine, so it was something in one of the updates that caused and issue.
I have the following setup:
Linux Mint 20.3
KDE Plasma Version: 5.68.0
KDE Frameworks Version: 5.68.0
Qt Version: 5.12.8
Kernel 5.4.0-135-generic
OS Type 64-bit
