[Bug]: Latest CLI cannot run shopify theme dev with theme blocks in /blocks folder

[gideonb]

Expected behavior

When I run shopify theme dev on previous versions from late fall I don't have issues.

Actual behavior

When I run shopify theme dev on the latest version 3.73.2 with a theme that contains nested blocks I get an INTERNAL_SERVER_ERROR

EDIT:
Not CLI's fault just bad schema code somehow causing a 500

Turns out it was just bad schema code and confusing error output. Closing issue.

This was the schema issue=>fix if anyone runs into this later -- a second array in settings causes chaos.

Reverting to the ruby version (3.69.4) gave me a filename and it was an easy find/fix from there. Latest version of CLI worked after fixing the issue.
