You might be able to swap the order of the schemas in the intersection, not sure if that would work. Alternatively, you could extract the known schema to a variable and exclude that way: 
const knownKeysSchema = z.object({
  knownKey: z.string(),
});

const schema = z.intersection(
  z
    .record(z.string())
    .superRefine((obj, ctx): obj is ObjectWithMetaFields => {
      const keys = Object.keys(obj).filter((x) => !(x in knownKeysSchema.shape));
      const invalidKeys = keys.filter((x) => metaFieldRegex.test(x) === false);

      if (invalidKeys.length > 0) {
        ctx.addIssue({
          fatal: true,
          code: "unrecognized_keys",
          keys: invalidKeys,
          message: `Meta fields must match the regex: ${metaFieldRegex.source}`,
        });
      }

      return z.NEVER;
  }),
  z.object({
    knownKey: z.string(),
  }),
);
const knownKeysSchema = z.object({
  knownKey: z.string(),
});

const schema = z.intersection(
  z
    .record(z.string())
    .superRefine((obj, ctx): obj is ObjectWithMetaFields => {
      const keys = Object.keys(obj).filter((x) => !(x in knownKeysSchema.shape));
      const invalidKeys = keys.filter((x) => metaFieldRegex.test(x) === false);

      if (invalidKeys.length > 0) {
        ctx.addIssue({
          fatal: true,
          code: "unrecognized_keys",
          keys: invalidKeys,
          message: `Meta fields must match the regex: ${metaFieldRegex.source}`,
        });
      }

      return z.NEVER;
  }),
  z.object({
    knownKey: z.string(),
  }),
);

If you wish to get more type safety, here is something: https://tsplay.dev/N5oVdW

You would intersect your known object with the "unknown" record just like in pure types. Here's a playground for one of the implementations: https://tsplay.dev/ND9Ajm

Perhaps you're looking for: 
const schema = z.literal("").or(z.string().email());
const schema = z.literal("").or(z.string().email());

Your form most likely is not passing null or undefined, most likely you have ""
