Error: Call to a member function __tostring() on string in Drupal\layout_builder_restrictions\Plugin\LayoutBuilderRestriction\EntityViewModeRestriction->blockAllowedinContext()

I haven't been able to find an exact pattern for when this happens, but sometimes when reordering blocks in LB I get an AJAX error printed in the browser console. It most recently happened with a views block but I don' t know if that specifically is causing the issue.

The block appears to move, but when I save the layout it's position doesn't in fact save and the following is printed in the watchdog log:

When I try and re-order the block via the "move" contextual menu option the settings tray form won't work when clicking the "update" submit button.
