cannot start up InDesign CC 2017 after install plugin [Closed]

cannot start up InDesign CC 2017 after install MainType 8 plugin.
InDesign CC 2018 works perfect after install MainType 8 plugin.
Deinstall MainType 8 plugin can start up InDesign CC 2017 back again.

I’m sorry about the inconvenience. Does InDesign show an error message?

When start up InDesign the start up screen shows initialization… and stops without error message.

We’ll contact you to see if we can find a solution.

after install recent update MainType 8.0.0.1132, I also cannot start up InDesign CC 2018 with plugin anymore.
It works perfect without Font Handler plugins.

That is really strange as the plugin hasn’t been changed.

Maybe your anti-virus software is causing the problem.
