SAML login enforcement creates error with just-in-time provisioning

We are using the Matomo cloud, I configured the SAML authentication with just-in-time provisioning.

The problem is now that I cannot modify the configuration to disable SAML enforcement.
Can anyone help me with this one?

error message:
ust-in-time provisioning error. Email already exists, can’t create an account for
