Is there a way to disble automatic plugin insertion into Photoshop CS6 or any Photoshop Version?

I have the case where I installed PR2019 and it automatically added plugins to Photoshop CS6 (I have a forever license). Immediately after installation, Photoshop stopped saving images to disk and gave a "I can't save that" error. I renamed the plugins to no success. Eventually, after totally uninstalling 2019, Photoshop began working properly again.

I found running 2019 to be slow, but everything thing seemed to work.

I have an older system, some of which is minimal for 2019, but all the other editing programs I use work very fast.

Adobe Photoshop Version: 13.0.1 CS6
Video Card: NVIDIA GeForce GTX 1050 Ti with 4 GB
16GB memory
Intel i5-3570K CPU @ 3.40 GHz
Windows 10 Pro
Version 1803
OS build 17134.345

It would be really nice if ON1 had the choice on installation to install the plugins or not, like other software does, in order to help work troubleshoot.
