Unused entites not working

Configuration
1

Hi, i’m having some trouble getting the Unused devices to show in lovelace, config checks are valid.
This has been working previously

Dev console shows the following error:

Uncaught (in promise) TypeError: obj.entities.forEach is not a function
at addEntities (f98c2ed66c0dc1462a8d.chunk.js:1)
at obj.cards.forEach.card (f98c2ed66c0dc1462a8d.chunk.js:1)
at Array.forEach ()

at Array.forEach ()
at computeUsedEntities (f98c2ed66c0dc1462a8d.chunk.js:1)

Any pointers on how to debug this?

Nevermind, i found the culprit
Seems like the flex-table-card i added recently messed it up.
