How do I prevent the program, "magnus," from popping up upon every login?

I am running Ubuntu Studio 21.10 on Kernel Version 5.13.0-2-lowlatency (64-bit);KDE Plasma & Frameworks versions are 5.22.5 and 5.86.0, respectively. Qt is version 5.15.2.

The system is AMD w/ 8 GB RAM.

I don't recall doing anything to tell magnus to pop up and annoy me each time I log in.

It is not in the usual "Startup" system setting dialog.

I'm unaware of other "startup" settings where it may be hiding.Do you know where/what I need to modify to prevent this tool from popping up without being requested.
