Hi,

My projects in Themebuilder breaks whenever I try to change the font size!

Steps to reproduce the error:

1. Create a new project (Font icons, Q4 2025 latest, Bootstrap)
2. Click on "Project setting".
3. Click on "Metrics".
4. Change:
   1. $kendo-font-size-md: 0.875rem
   2. $kendo-font-size-sm: 0.75rem
   3. $kendo-font-size-xs: 0.625rem
      
      
      
5. Close project settings.
6. Now the project is broken.
   1. Crash in javascript console:
      Uncaught _P: There are errors in SASS and it cannot be compiled to CSS.
      PATCH https://themebuilderapp.telerik.com/api/v1/projects/6928717ab857146bc01d9a2e/variables 500 (Internal Server Error)
      
      
   2. The project cannot be saved:
      
      
7. It is no longer possible to load the project. The same error appears in the console as shown above.
8. If I export the metadata from this broken project from the Dashboard and import it into a new project, that project also breaks. I have attached the metadata.

Please help!
