F28 Openshot not starting. How to troubleshoot?

edit

I am running F28/KDE. I installed openshot from the repos. It failed to start. The output is below.

During handling of the above exception, another exception occurred:

I have 2 questions:

1) How to troubleshoot? I have minimal experience with linux troubleshooting. Where do I start? How/where to learn?

2) How to fix?

FYI: I have a F28/KDE minimal VM. Installed and ran from repos fine.

Sorry for formatting. First time poster.
