I'm getting the following error:

TypeError: Right-hand side of 'instanceof' is not an object
 ❯ cloneObject file:/home/.../node_modules/.pnpm/react-hook-form@7.31.3_react@18.1.0/node_modules/react-hook-form/dist/index.esm.mjs:574:55
 ❯ createFormControl file:/home/.../node_modules/.pnpm/react-hook-form@7.31.3_react@18.1.0/node_modules/react-hook-form/dist/index.esm.mjs:1347:26
 ❯ Module.useForm file:/home/.../node_modules/.pnpm/react-hook-form@7.31.3_react@18.1.0/node_modules/react-hook-form/dist/index.esm.mjs:2203:16

which points to the following line in react-hook-form:

!(isWeb && (data instanceof Blob || data instanceof FileList)) &&

It looks like FileList is being evaluated as undefined.
