Opened a new project and added one of each different item types available to check their differences.
After some point, all designer windows were replaced by an error indicating that the designer cannot be opened before an error is resolved: Unexpected token: }. Looking for :.
The stack info for the error is:

Thank you. The issue was probably caused by the mixin template. We’ll check and fix.
There is a short overview document about the theme system including mixins here: https://wisej.com/themes/
A mixin definition can also inherit from the base theme and extend or override.
Add this file under \Themes with the name “my-button.mixin.theme” and paste in the JSON below including the curly brackets.
I saw this issue with the older beta version, before the current (80). Unfortunately I have deleted the problematic project and haven’t tried to reproduce it either. I saw the comment about mixins, I had indeed add a “theme mixin” (what is a mixin anyway, I don’t have a clue!).
