Could you have a look of your environment and check if one of the cases below applies?
Someone seems like solve the same problem by deleting the existing key and reissuing the key.
reCAPTCHA ERROR: Invalid domain for site key
Using reCAPTCHA on localhost: This question below says that there is a possibility that you need to reissue, if you migrated from the V1 to V2.
And one of the comments in this question also suggests you may need to add a different name, not localhost.
I personally used reCaptcha and reCaptchaV2 and never came across this problem, and noticed that I always used a domain name specified by hosts file(/etc/hosts) even if it run in my localhost.
