This likely means that the library (@angular/material/form-field) which declares MatFormField has not been processed correctly by ngcc, or

is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.
