Frontend crashes due to faulty configured card - any ideas?

Hi guys,

Iam using the ApexCharts as Frontend Lovelace Addon. Today I misconfigured an ApexCard.
Now everytime I open the dashboard page where the card resides in, it crashes.
I cant click on anything. Even when I use the direct edit url (/lovelace-board/subpage?edit=1) I cant click aynthing. How can I remove the faulty card? Whatever I do - whenever I visit the dashboard page everything freezes. No change for deletion or changing anything.
I don’t want to remove the total dashboard page as I have dozens of specific configured apex cards in it.
How can I remove the faulty one?
