I'm having the same problem. Tried what you mentioned and still nothing.

Hi there!
Please, send me a screenshot of the error log of your problem and tell me what RPG Maker version(MV or MZ) are you using. Make sure to download the latest versions of the plugins too.
If you checked everything above, I guess that is the only option left:
"I believe the error has to do with some wrong data set on some note tag. Like you need to use <DynParams:TemplateName> on the equipments or state note fields. The problem may be that some template name is not matching the plugin parameters or it is a number. How did you setup your dynamic parameters on the note fields?"
When the error is happening for you? As soon as you start the game? Or in an specific moment?
