G'mic plugin 2.9.1 for gimp 2.10.20

[sgtisixpack]

I was watching this tutorial and he suggested G'MIC.  There is a filter called debanding noise, I need it badly.  I was trying to do it manually but I can see the previews are working.  Just the plugin has errors and crashed once.  I really need this or a filter from another plugin that works in 2.10.20.  I installed it to the default location.  Here is a screenshot of the error ( I had a different error with a different filter but this filter is what I needed).

And the before and after screenshot (preview can show "difference").
