I found a bug with adding my own projects to public studios.

When I add one of my shared projects to a public studio, it appears to be added successfully. However, after I refresh the studio page, my project disappears.

This happens with my own shared projects, but projects made by other users remain in the studio after refreshing.

There is no warning or error message.

Steps to reproduce:

Open a public studio.
Add one of my shared projects.
The project appears in the studio.
Refresh the studio page.
The project disappears.

I tested this with multiple shared projects. The problem also happens when browser extensions are disabled.

Browser: Chrome 151.0.0.0
OS: Windows 10`
