Financing and partial cascade requirement

I have financed a car and have now found in the contract that a full or partial cascade insurance is necessary for the contract to be valid. However, I have already got the car and not a full or partial cascade. Only a liability. Can it happen now that the financing by the bank is dissolved? I am afraid that they then say, then the contract will be dissolved by the bank. I also have so far only the loan application before the bank But then I wouldn’t get the car or? Is my first financing therefore my (doofen) questions
