Error if Layout Builder is enabled

Hi @finex,
Could you please provide the step to reproduce the issue as I've enabled both the modules(Layout Builder, LinkChecker) and I've addded a link field in the Article and managed its layout through layout builder but I didn't get any error.

I think this actually has to do with missing database updates, and not layout builder. I had the same problem on saving a media entity (no layout builder), but realized I hadn't run database updates.
