a number of errors related to osascript are display but more interesting is what you get if you open the detailed report you get. Start the console.app and check what is happening when performing this action.

I found a work around that worked in my case that could be useful to experiment. I was experiencing the same problem than you even with the latest version 15.21.1, havingĬheck spelling and grammar correctly marked with squiggly lines, but right click selection not working (freezing for a few seconds).
