Bookmarking a question stops loading Metabase UI

Tried to bookmark a question in Metabase version: 0.46-RC3.

After bookmarking one single question (written in native SQL) causes this error:

Output of normalize-bookmark-result does not match schema

Metabase UI doesn't load:

There is an API: Bookmark. One option is to remove bookmark by using API DELETE /api/bookmark/card/776

What is the easiest way to remove a bookmark for my user?

Just to confirm: I sent the API request DELETE /api/bookmark/card/776 from Postman and Metabase UI started working.

hey, interesting find although I'm not able to replicate it. Are you able to replicate it with the sample database?
