Greetings @wangjun5ren and Welcome! This is usually a temporary issue due to a change or update or addition you have made to a record. The prior change is processing and therefore you can't make another until it resolves. If you have waited some time (say long enough to make a cup of coffee or tea) and you still see the message after refreshing the browser, do as it says and contact support.
