[bug] Opening Project Stuck at "Starting your app server..."

[nicoencarnacion]

Bug Description (required)

I am trying to open a project that I initially built using Lovable and continued building using Cursor. But when I try to open it in Dyad, it's just stuck at "Starting your app server..."

I cannot refresh the preview and I cannot open the app in the browser as well.

Steps to Reproduce (required)

Just open a local project. Project was built using:

• Vite
• TypeScript
• React
• shadcn-ui
• Tailwind CSS

Expected Behavior (required)

Preview should run and I should be able to refresh and open app in browser.

Actual Behavior (required)

Preview is stuck at "Starting your app server..."
