Spinning ball issue on IMac 5K late 2015 running Mojave. Etrecheck included.Can anyone tell me what next to troubleshoot?

Uninstall the Bitdefender antivirus software according to the developer's instructions: How to uninstall the New Bitdefender Antivirus for Mach. It is not necessary for Macs as there are no know viruses for Macs.

Uninstall Disk Doctor, MacFly Pro. Cleaning apps are not needed nor are "optimizing" apps. Contact the developer's for instructions on manually removing the app and it's support documents.

You can see for yourself "Bitdefender" is occupying an inordinate amount of your Mac's resources, consuming energy, and crashing. That's all it will ever do. I was under the impression that's something a computer virus does.

Don't use Western Digital's "drive manager" products either. They provide no beneficial function. Early versions of their software had the undesirable side effect of erasing hard disk drives.

Are you still using a BlackBerry? At least their software isn't crashing.
