Thanks for the update, unfortunately it is still crashing for me, I can install the plugin and click on “Make it so!” button but if I try to open the options again Picard crashes. I’m using Windows 10.
But I found out it only crashes if the dark theme is enabled (at least using the default value), if I install the plugin and at the same time change the theme to light, close and reopen Picard the options window is opened successfully, then if I change the theme back to dark theme it doesn’t crash anymore.
Now I’ve tried to reproduce the error and I can’t. I tried deleting the plugin, changing back the theme to “default”, reopening Picard, installing the plugin, open options again and… it doesn’t crash anymore. It made it crash before (I tried reinstalling the plugin ~5 times before changing the theme and in all of them Picard crashed).
