@andrelopez Just updating this - it seems making any change to a payment form or creating a new payment form causes this error...so payment forms can no longer be created at all...

Just to update this as per the error above this seems to be to do with Stripe Connect...I deleted all my connect data and turned off connect (turning off by its self didn't help) and now I am able to use payment forms again....
