I thought I would share how I have resolved my problem with Styler Toolbar killing WindowBlinds on startup so that if anyone else in the future experiences this problem, they can try the information below as one thing they can do and perhaps resolve it.
The "fix" seems to have been to start the "Theme" service and set it to "Automatic". This particular service I had stopped and and set to "Disabled" quite some time back since it isn't needed when using WindowBlinds and if you don't intend to use the default Windows "Luna" theme. But apparently, it has to be running for Styler to load correctly on startup.
I've rebooted several times now and Styler loads without effecting WindowBlinds. So, at this point, I am considering this issue RESOLVED!!
