Unable to recreate code component with same name after deletion

I was able to reproduce this issue as described.
Steps followed:

- Created a code component named "myCode".
- Added it to the component list.
- Deleted the "myCode" component from the list.
- Tried to create a new code component with the same name "myCode".

The error message appears: "Cannot read properties of undefined (reading 'startsWith')" and the creation fails.

This seems like a bug in how deleted component names are handled in memory or state.

Based on the title I expected this to be a back-end bug, though I wondered how that could be the case. But the error message suggests this is a pure client-side bug?

"When we create a component with the same name as one that was previously deleted, an error is thrown as described in the summary. However, after reloading the page, the component appears to have been successfully created. I believe there may be an issue with the error handling in this case.

I’ll try to look into it, but as I’m new to Experience Builder, it would be great if someone could help me locate the relevant part of the code.
