How to Disconnect a Squarespace Domain from Carrd?

I’ve been trying to remove a Custom Record from the DNS Settings in Squarespace, but every time I attempt it, I receive this error message:

“Custom record couldn’t be deleted. We were unable to delete this record. Try again later. If this problem continues, contact Customer Support.”

I’m currently stuck on this issue. I’ve already reached out to customer support for both Carrd and Squarespace, but I’m unsure if they’ll even respond.
