I found the issues: Path: JRootcomponents/com_users/forms/reset_request.xml

Correct xml code:

<?xml version="1.0" encoding="UTF-8"?>
<form>
    <fieldset name="default" label="COM_USERS_RESET_REQUEST_LABEL">
        <field
            name="email"
            type="email"
            label="COM_USERS_FIELD_PASSWORD_RESET_LABEL"
            required="true"
            size="30"
            validate="email"
            autocomplete="email"
        />

        <field
            name="captcha"
            type="captcha"
            label="COM_USERS_CAPTCHA_LABEL"
            validate="captcha"
        />
    </fieldset>
</form>
